摘要：In this paper, inspired by the work of Fort, the stability of the set F(f) = {y is an element of X : sup(x is an element of X) f(x, y) less than or equal to 0} (respectively, the set F(A, f) = {y is an element of A : sup(x is an element of A) f(x, y) less than or equal to 0}) with f varying (respectively, with both f and A varying) is studied where X is a non-empty compact convex subset of a Hausdorff topological vector space (respectively, X is a Hausdorff topological space and A is a non-empty compact subset of X) and f : X x X --> R is bounded.
