Fourty most significant publications

It is always difficult to decide which are your most significant publications, as some oustanding work may be displaced. Here I have chosen those that I feel are the most important while representative of my broad range of interests. These are not necessarily my most highly cited papers, and indeed here I have displaced papers that have been highly cited: specifically I have displaced 6 papers that have been cited 279, 273, 255, 195, 179, and 167 times, respectively, by ones that have been cited 14, 11, 5, 4, 3, and 2 times. I have found that citations sometimes increase dramatically once the significance of the result becomes appreciated [this was especially true of papers (15) and (16) below]. My total citation count of 11,100 (”h-index” of 51) is high for a mathematician.
