Algebraic and topological properties of some sets in $l_{1}$

T. Banakh, A. Bartoszewicz, Sz. Glab +1

For a sequence $x \in l_{1} ∖ c_{00}$ , one can consider the set $E (x)$ of all subsums of series $\sum_{n = 1}^{\infty} x (n)$ . Guthrie and Nymann proved that $E (x)$ is one of th…

The continuity properties of compact-preserving functions

Taras Banakh, Artur Bartoszewicz, Marek Bienias +1

A function $f : X \to Y$ between topological spaces is called {\em compact-preserving} if the image $f (K)$ of each compact subset $K \subset X$ is compact. We prove that a function $f:…
