Let X be a reflexive Banach space and let Ф be an extended real-valued lower semicontinuous convex function on X. Given a real A and the sublevel set S = [Ф ≤ λ], we establish at x̅ ϵ S the following ...

Intrinsic volumes of convex sets are natural geometric quantities that also play important roles in applications, such as linear inverse problems with convex constraints, and constrained statistical ...
