Workshop on Metric Bounds and Transversality (WoMBaT 2016)


The meeting will be held in Melbourne (RMIT City Campus, room 8.9.66) on 24–25 November.

The topics of the workshop include error bounds, metric (sub) regularity, Aubin property and calmness, transversality of collections of sets, subdifferential characterisations and applications of these properties to estimating the convergence of fundamental optimisation algorithms. Our keynote is Professor Marco Lopez from the University of Alicante, Spain, who is visiting Australia in November.

Title: Subdifferentials of structured functions


I will talk about geometric construction of Fréchet 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 Théra satisfy such assumptions.

These results are in the same spirit as the classic expressions for the Clarke subdifferential in terms of quasidifferentials originally developed by Demyanov and Rubinov.

The talk will be based on some old papers and recent joint work with Tian Sang (RMIT University).
