Permutations preserving sums of rearranged real series

Roman Wituła (2013)

Open Mathematics

The aim of this paper is to discuss one of the most interesting and unsolved problems of the real series theory: rearrangements that preserve sums of series. Certain hypothesis about combinatorial description of the corresponding permutations is presented and basic algebraic properties of the family 𝔖 0 , introduced by it, are investigated.
