| I first met Louis Nirenberg in person in 1972 when I became a Courant Instructor. He was already a celebrated mathematician and a suave sophisticated New Yorker, even though he was born in Hamilton, Canada and grew up in Montreal. In this talk I will describe some of his famous papers, some of our joint work and other work he inspired. For reasons of exposition, I will not follow a strict chronological order and I will concentrate on some of Louis' work inspired by geometric problems beginning around 1974, especially the method of moving planes and implicit fully nonlinear elliptic equations. During the twenty year period 1953-1973 he produced an incredible body of work in many fields of pde including pseudo differential operators and local solvability. Of course I cannot begin to talk about this work. Louis loved to collaborate and I apologize for omitting many other important results of the last twenty five years, a majority of which were in collaboration with his brilliant and devoted student Yanyan Li. This is the opening talk of the 35th Annual Geometry Festival. http://www.math.stonybrook.edu/geomfest21/ | |
