On the ideal convergence of sequences of Świątkowski functions
Tomasz Natkaniec , Piotr Szuca
AbstractFor any Borel idealIthe class of I-limits of sequences of ́Swiątkowski functions is described. In particular, we characterize Borel ideals I for which classes of ideal and ordinary limits of sequences of ́Swiątkowski functions coincide. We consider also ideal limits of sequences of functions possessing the ́Swiątkowski property related to some density-type topologies. Moreover, an alternative characterization of ordinary limits of sequences of ́Swiątkowski functions is given.
