Sažetak

We identify a general reordering principle for well-ordered series in Banach spaces. We prove that for every absolutely convergent wellordered series indexed by a countable ordinal, if the series is rearranged according to any countable ordinal, then the absolute convergence and the sum of the series remain unchanged.

Ključne riječi

Well-ordered series: summability; absolute convergence; reordering; Banach spaces; ordinals.
