A remark on optimal weighted Poincaré inequalities for convex domains (1207.0680v2)
Published 3 Jul 2012 in math.OC and math.CA
Abstract: We prove a sharp upper bound on convex domains, in terms of the diameter alone, of the best constant in a class of weighted Poincar\'e inequalities. The key point is the study of an optimal weighted Wirtinger inequality.
