Compactness in spaces of functions of bounded variation from ideal perspective
Jacek Gulgowski, Adam Kwela, Jacek Tryba
Recently we have presented a unified approach to two classes of Banach spaces defined by means of variations (Waterman spaces and Chanturia classes), utilizing the concepts from th…

Compactness in the spaces of functions of bounded variation
Jacek Gulgowski
Recently the characterization of the compactness in the space of functions of bounded Jordan variation was given. Here, certain generalizations of this result are given…
