Abstract

Modern nonsmooth analysis is now roughly 35years old. In this chapter, I shall attempt to analyse (briefly): where the subject stands today, where it should be going, and what it will take to get there? In summary, the conclusion is that the first-order theory is rather impressive, as are many applications. The second-order theory is by comparison somewhat underdeveloped and wanting of further advance.

This chapter is dedicated to Boris Mordukhovich on the occasion of his 60th birthday. It is based on a talk presented at the International Symposium on Variational Analysis and Optimization (ISVAO), Department of Applied Mathematics, Sun Yat-Sen University, 28–30 November 2008.
