Abstract
The notion of beta(1)-paracompactness in topological spaces is introduced and studied in [1]. In this paper, we introduce and investigate the notion of beta(1)-paracompact spaces with respect to an ideal I which is a generalization of the notion of beta(1)-paracompact spaces. We study characterizations, subsets and subspaces of beta I-1-paracompact spaces. Also, we investigate the invariants of beta I-1-paracompact spaces by functions.
