Hahn-Banach theorems for -normed spaces
arXiv:math/0301197
Abstract
For a new class of topological vector spaces, namely -normed spaces, and associated quasisemilinear topological preordered space is defined and investigated. This structure arise naturally from the consideration of a -norm, that is a distance function between a point and a -subset. For it, analogs of the Hahn-Banach theorem are proved.
