Subdifferential Calculus Rules for Supremum Functions in Convex Analysis
Chong Li, K. F. Ng · SIAM Journal on Optimization · 2011
Extending and improving some recent results of Hantoute, López, and Zălinescu and others, we provide characterization conditions for subdifferential formulas to hold for the supremum function of a family of convex functions on a real locally convex space.
