Virtual Inst. 9, No. 2, 271-280 (2019). Summary: In this paper, the concepts of \(\mathcal{I}_{wg}\)-closed sets and \(\mathcal{I}_{wg}\)-open sets are introduced and they are used to define and investigate a new class of functions called contra \(\mathcal{I}_{wg}\)-continuous functions in ideal spaces. We discuss the relationships with some other related functions.
