WebThe Schauder fixed-point theorem is an extension of the Brouwer fixed-point theorem to topological vector spaces, which may be of infinite dimension.It asserts that if is a nonempty convex closed subset of a Hausdorff topological vector space and is a continuous mapping of into itself such that () is contained in a compact subset of , then has a fixed point. WebInterestingly, the vertices of a triangulated planar convex form the oriented multiplicative group structures. The surjectively identified planar triangulated convexes in a locally homeomorphic subspace maintain path-connection, where the right-identity element of the quasiloop–quasigroupoid hybrid behaves as a point of separation.

WebApr 1, 1972 · Let K be a nonvoid compact subset of a separated locally convex space L, and G : K K be an u.s.c. multifunction such that G(x) is closed for all z in K and convex for all x in some dense almost convex subset A of K. Then G has a fixed point. Proof. Let i^ be a local base of neighborhoods of 0 consisting of closed convex symmetric sets. WebJun 5, 2024 · One quite important branch of the theory of locally convex spaces is the theory of linear operators on a locally convex space; in particular, the theory of compact (also called completely-continuous), nuclear and Fredholm operators (cf.
