Another characterization of meager ideals

HIGHLIGHTS

  • who: Marek Balcerzak from the Institute of Mathematics, Lodz University of Technology, alPolitechniki, Lodz, Poland have published the article: Another characterization of meager ideals, in the Journal: (JOURNAL)
  • what: The authors show that an ideal I on the positive integers is meager if and only if there exists bounded nonconvergent sequence x such that the set of subsequences of x which preserve the set of I -limit points is comeager and in addition every accumulation point of x is also an I -limit point (that is limit of subsequence (x n k ) such that {n . . .
