PIMS/WMAX Postdoctoral Colloquium: Hung Phan Minh

Abstract:  In this talk, I introduce the restricted normal cone, which is a novel generalization of the Mordukhovich (also known as basic or limiting) normal cone. Basic properties are presented. In the case of subspaces, we make a connection to the Friedrichs angle between the subspaces.  Restricted normal cones are useful in extending work by Lewis, Luke and Malick on the method of alternating projections for two (possibly nonconvex) sets.

Based on joint work with: Heinz Bauschke (UBC Kelowna), Russell Luke (Goettingen, Germany), and Shawn Wang (UBC Kelowna).
