Some remarks on stronger versions of the Boundary Problem for Banach spaces

Jan-David Hardtke

Let $X$ be a real Banach space. A subset $B$ of the dual unit sphere of $X$ is said to be a boundary for $X$ , if every element of $X$ attains its norm on some functional in $B$ . Th…

Rainwater-Simons-type convergence theorems for generalized convergence methods

Jan-David Hardtke

We extend the well-known Rainwater-Simons convergence theorem to various generalized convergence methods such as strong matrix summability, statistical convergence and almost conve…
