Title: Calculus rules for subdifferentials

Abstract: Subdifferentials generalise the notion of derivative for functions which are nonsmooth. There are different ways to define such generalisations. I will talk about geometric construction of Fr├ęchet and limiting subdifferentials for finite minima of functions subdifferentiable in the sense of Demyanov-Rubinov. Such functions have convex directional derivatives and under additional assumptions their subdifferentials preserve enough directional information to make such construction possible. For instance, approximate convex functions introduced by Huynh Van Ngai, Dinh The Luc and Michel Thera satisfy such assumptions.
