P. Vojčák Mathematical Institute, Silesian University in Opava
Abstract:
We introduce the notion of Hyers–Lang tangent cone to a subset of a topological vector space, and give a characterization, for the case of locally convex topological vector spaces, of Hyers–Lang differentiability in terms of the Hyers–Lang tangent cone to the graph.
Keywords:
Hyers–Lang differentiability, Hyers–Lang tangent cone, locally convex topological vector space, balanced neighborhood.
