“…Let d=l, S=(-1,11, a(') a 1, F(x,y) = y for all x, and the cost functional [20] to prove that g(x,') remains equicontinuous bounded on compact subsets of G\{x}. It is not hard to deduce from this that the attainable g(x,') form a compact set C x in C(G\{x}) and the bijection yx --g(x,') is a homeomorphism between Mx and Cx.…”
