The concepts of fuzzy regular-I-closed set and fuzzy semi-I-regular set in fuzzy ideal topological spaces are investigated and some of their properties are obtained. Key words: Topological, Spaces, Fuzzy, Regular, Sets

In this paper, we prove a common tripled fixed point theorem for Jungck type mappings in G-metric spaces. We give an example to illustrate our result.Keywords: G-metric space, Jungck type maps, tripled fixed point, W*-compatible maps..MSC: 54H25, 47H10.

In this note, we  investigate extensions of Baer and principally projective modules. Let  R be an arbitrary ring with identity and M a right R-module. For an abelian module M, we show that M is Baer (resp. principally projective) if…
