The analysis is obtained through a comparison with the related level convex prob- lem and written in terms of a di fferential inclusion involving the boundary data. Several conditions of convexity for the supremand $f$ are also studied.This is a joint work with Ana Margarida Ribeiro.Recording (avi): http://mm.math.cmu.edu/recordings/cna/CNA-ElviraZappaleTape-Apr-08-2014.aviRecording (mp4): http://mm.math.cmu.edu/recordings/cna/CNA-ElviraZappaleTape-Apr-08-2014.mp4Date: Tuesday, April 8, 2014Time: 1:30 pmLocation: Wean Hall 7218Submitted by:  David Kinderlehrer
