Ideal boundedness of subseries and rearrangements in Banach spaces vs Banach spaces possessing a copy of $c_{0}$

Michał Popławski

Suppose that $X$ is a Banach space. We will show that $X$ does not contain a copy of $c_{0}$ if and only if for each series which is not unconditionally convergent in $X$ respective…

Ideal convergent subseries in Banach spaces

Marek Balcerzak, Michał Popławski, Artur Wachowicz

Assume that $I$ is an ideal on $N$ , and $\sum_{n} x_{n}$ is a divergent series in a Banach space $X$ . We study the Baire category, and the measure of the set $A(\mat…
