Old age blues
Last few weeks I have been thinking of accessibility of finitely presented groups proved by Martin Dunwoody in 1983. I thought about it around 1974 and had the right ideas. But at that time algebra was not really my area and I gave up on some good problems after getting the right ideas. I also thought that may be one can use minimal surfaces but knew very little of the area. I gave a talk in Stoney Brook around 1979-80about it and Gromov was in the audience. Then after coming to Melbourne, in random browsing of our departmental library, I saw a volume in honour of some mathematician, may be I.M. Gelfand, and there was a paper by Gromov proving accessibility using minimal surfaces in higher dimensions. I even remember he used dimensions bigger than 6. I have a visual memory of the book and the paper.
Recently, I started thinking about it since Peter Scott with me and two others developed an analogue of minimal surfaces for groups. I tried to ask friends about it but nobody knows about Gromov’s proof. Meanwhile our departmental library closed and the books were sent other libraries in the University. I cannot find the book.
I wonder what is happening. Did I imagine all this. My working on mathematics is very haphazard. I basically learnt by myself. It was more passion than ambition. So there are lot of gaps in my knowledge of the areas I work. I often follow the general outline and try to fill the gaps later. For example, I did not read some of Waldhausen’s papers in 1969 but found simple proofs around 2002. I do not know whether it is one of those things or whether I really imagined the whole thing. I wrote to Gromov yesterday and I do not know whether he will reply.
It surprises me that i did and can do some mathematics. I have no confidence in my abilities or any ambition. But if some thing bugs me, I keep thinking about it sometimes for years. I have also been lucky with collaborators, that after the age of 45 or so. But I did a few interesting things before. Anyway, I am puzzled by how I have been able to do some mathematics and even made a living given that I come from a farming family.

some suggest that US has been looking for an exit from the Ukraine conflict and this lrovides with various further possibilities. But so many Israeli casualities do not suggest a deliberate neglect; though it is possibilities that it exceeded expectations.it may delat Saudi-Israeli rapproachmdnt which may point the finger at Iran. Again it may spoil the relations between Saudi Arabia and iran and provide a way to disrupt Brics. Nobody seems to know and all seem to agree that it is bad news which will lead to worse things to come.

Painful as it might be for us to take some of the obviously deliberate provocations ‘on the cheek,’ good chance remains that sometime in the future, after Ukraine’s rapid disintegration and subsequent capitulation—perhaps even only a year or two from now—we may recognize, in hindsight, the wisdom of the strategy which staved off nuclear war by way of a methodical, unwavering, and strategically disciplined approach."

My first trip to the west
From Facebook:
Ramarao’s post below reminded me of my first trip abroad to England in 1968. My English was poor (then and now) even by Indian standards and the first problem was English. I grew up in villages, studied in Telugu medium. When I went to study in Madras, the college authorities appointed an English tutor to coach me. It did not have much effect I think. I had the naïveté and stubbornness of the farming community I came from and was not fazed by what others thought of me. The reason for going to England was mathematics. When I was in Madras, I came across a book called ‘Set Theory’ by Felix Hausdorff and Brouwer’s theorems fascinated me. And I decided to learn topology. When I Joined Tata Institute, MS Narasimhan took some interest in me perhaps because he too grew up in Andhra for a few years. After I showed some promise he decided that I should go abroad for further studies.
When he asked me where I wanted to go, I said Liverpool because I already read several papers of C.T..C. Wall. Then I got a Nuffield Fellowship after a bit of coaching by him and landed in London. If language was problem, food was more difficult. Only thing I could eat was toast and butter and coffeee was undrinkable. It was cold; it was September I think, and Nuffield people gave me some money to buy warm clothes and sent me off to Liverpool. By that time there was no place in university hostels and Wall took me home. Though one read books and saw films about foreigners, I did not really know or was coached about everyday living. MSN greatly neglected this aspect. I did not really understand the sleeping arrangements. I just covered myself with the bed cover and it was still cold and kept the heater on through out the night. Instead of a shower, there was a bath which I did not know how to use. But the food was better than in the hotel. The family must have got tired of cleaning the bath tub and after a couple of weeks, they found me accomodation in a seminary, where there were plenty of rooms since theology was not too popular. Thus my sojourn abroad started.
A bit more about my life in Liverpool. Life in the seminary was good. The students showed me how to get in to the bed and how to make the bed. The food was ok. Not all the students believed in god. They introduced me to Bob Dylan and the pub culture. Terry Wall ( coming from india it was difficult to call him by his first name which I generally avoided) told me what I did was enough for a ph.d. So I took it easy and read what I liked and made friends in the department. One of the
things I read was Wall’s long paper which was coming out then called ‘Surgery on non simply connected manifolds’. I even gave a course on it in Yale. I do not know how much I understood. Kervaire who listened to a lecture by me later told Raghavan Narasimhan that I did not know what I was talking about. But the English do not tell you that you are a fool even if they think you are. So I got along splendidly.
I started going out with students for dinners and with some staff for lunches. With students I often went to Indian restaurants where the food was not that good. I asked the staff why they were making such food which was not really Indian. They said that it was the way the English liked it but they made a separate curry for themselves called ‘staff curry’. From then on we started having staff curry and the food problem was partially solved. The food situation has improved considerably since then.
Soon I met a girl and it seemed better to shift from the seminary and I shifted to a room near Sefton Park from Birkenhead. I thought I was too old to fall in love. My office was next to women’s toilet and soon I started recognising her presence by the way the taps turned in the toilet. By the time I realised that I was in love, it was too late and it was time to leave Liverpool for Yale in America. So the last few months in Liverpool were tough.
Even though I was always a bit rebellious, it was only in Liverpool that I realised how Indian I was. The first few months were lonely. I always hated Indian classical music and dance for what I considered gymnastics. But Ravi Shankar came to Liverpool and I attended the concert with John, an American. He thought that it sounded like cows mewing but it was all very sweet and like homecoming to me. Also I met Jo Marks and Peter Scott there and the friendships endure to this day. But Jo refuses to tell me any thing about that girl.

it containa bit about our common teacher M.S.Narasimhan. MSN was my ph.d advisor but i was already interested in topolgy and worked by myself. we used to have beer on Daturdays for a while. He was like an older brother to me and was responsible for my trip to Liverpool.
Revenge mathematics
Revenge mathematics. I think that it was 1977, I visited England for a conference. There are some memories, but I may be mixing up with another conference. May be it was the conference Serre lectured and lights went out but he went on with the lecture. I was going back to india but stopped to visit a friend Jo Marks in Southampton. On the way, I stopped in London to visit Dillon’s, a bookshop which had a reasonable collection of mathematics books. Just then a book on 3-manifolds came out and I bought. As I browsed the book, there were no references to me though there were references to others who did similar work. I was upset and angry. On the train to Southampton, I started looking at open problems in the book( I think that I ended up solving some of them) and one caught my attention. It was about finding criteria for a surface subgroup of a compact irreducible manifold to be peripheral. I found a cohomological criterion for sufficiency and by the time I landed in Southampton, I had a theorem ready. But it was too easy and I was not sure whether it was publishable. Somedays later I realised that it was an important special case of a theorem of Johannson and he actually ave me preprints in 1974 in Bielefeld. and I happily published a two page note. It brought some attention but I could not prove the full Johannson theorem. It seemed to need a relative version of what I did.
Much later I started working with Peter Scott and had a joint paper with Peter which was mostly his. He asked me to prove the relative version and it came immediately. Instead of some coholomogy group being zero, it needed a map in some cohomological groups to be the zero map. Peter completed the proof of Johannson’s theorem using some easy three dimensional topology. This was around 2000.
I thought that was the end of it. Meanwhile we studied this kind of decompositions of Poincare Duality pairs and around 2019, we started wondering whether an analogue of Johannsion’s theorem was true for them. And in a few days a proof popped up. And it also gave a simple algebraic proof for 3-manifolds. Meanwhile fashion shifted and nobody noticed it though for us it was a pleasing conclusion after nearly 42 years. But I think that I have seen micro bundles, block bundles and various such fashions come and go but JSJ stayed for fifty years.
P.S. I tried a relative version of my argument for over twenty years but could not do it. Yet when Peter asked me do it, I did with in a day. May be there is some thing in collaboration that increases the intensity of the endeavour and makes two plus two bigger than four.

Reminiscences of Peter Scott
We first interacted in Liverpool during 1968-69 where we discussed mostly Kirby-Siebenman work. Later we seem to have independently turned to 3-manifolds and there was some correspondence in 1972 about Waldhausen’s work as well as ‘finitely generated implies finitely presented’ for 3-manifold groups. There is some discussion of this in a survey article by Danny Wise and probably the neatest proof comes from Thomas Delzant which I described ‘Delzant’s variation of Scott Complexity’ written in Peter’s honour on his 60th birthday.
Our next interactions were sporadic for a while. I remember Peter advising me that it is difficult to understand Thurston and that I should discuss with others. He then invited me to conference in 1984 that he organised with D.B.A. Epstein in Warwick. By this time he was quite well known and seemed to be determined to make a better mathematician out of me. We next met in Norman, Oklahoma in 1986, and he suggested two problems which we did together. One of them proved that certain finitely generated subgroups of distorted Kleinian groups are geometrically finite. Since then topic has been pursued by a few others. After that we met in a few conferences where we discussed how many results in 3-manifold theory may have analogues in group theory with annulus theorem as a possible candidate. But serious work on this started in 1994 when Peter visited Melbourne.
During this visit Peter showed me a paper of Tukia and said that it should lead to a proof of annulus theorem for hyperbolic groups and he also suggested that I needed to read only a few pages in Tukia’s paper. It was like a thesis advisor advising a student. This was the start of an intense collaboration with Peter since then. We probably wrote over six hundred pages of mathematics together in about ten papers. We made mistakes and probably took up a wrong program. But after a lot of hard work we did achieve what we wanted and for both us it seemed the hardest work we have done. We visited each other several times and it was not always clear how the ideas originated but they seemed joint. The program was the main aim, we did not care who did the actual work. Some papers were completely Peter’s and some more or less mine though they appeared as joint papers. Sometimes there were other collaborators. For both us it was very satisfactory work with the last paper just nearing completion. ‘Beating it in to shape’ as Peter used to say.
In retrospect, it seems to me that we were barking up the wrong tree though Peter did not agree with me. But along the way we did some work on intersection numbers and regular neighbourhoods which seem to be useful in other contexts too. Peter remained active until he could work no more. This last paper was written mostly by him. During this March-June, he developed another approach to regular neighbourhoods which is quite interesting and non-trivial.

About Gramsci
"Gramsci provides no easy answers for the current challenges that we face. Yet with concepts such as “hegemony” and “organic intellectuals,” the “war of position” and the “historic bloc,” “conjunctural analysis” and the battle for “common sense,” he provides social movements with an enriched strategic vocabulary. And with his insistence on rejecting determinism and engaging with society’s most deeply held beliefs, he offers an approach to radical politics that is dynamic enough to stay relevant through the crises—and transformations—yet to come." from https://www.nakedcapitalism.com/2023/08/what-can-social-movements-learn-from-gramsci-in-todays-uncertain-times.html
