Restricted p-Centers for Sets in Real Locally Convex Spaces
Numerical Functional Analysis and Optimization
Let p be a continuous seminorm on a real locally convex space X. The current paper is concerned with the problem of restricted p-centers in X. Characterizations of restricted p-centers and strongly unique restricted p-centers with respect to a "sun" are provided, and then some recent results due to Laurent and Pai  are extended and improved.doi:10.1081/nfa-200067302 fatcat:fysfuwrcfngyfpoqf374wxqxlq
