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. ...... The link below is the third of the papers. The first two papers are the references 20 and 16 there. https://arxiv.org/pdf/2006.15684.pdf

Peter Scott passed away

in the early hours of September 19. it is a great personal loss for me. we collaborated for over thirt years and our interactions went beyond mathematics. The memories of him will stay with me for the rest of my life.

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.
