On Some Maps Concerning Beta Closed Sets and Related Groups
3B1;-open, 3B2;-open and 3B2;-irresolute mappings
Abstract
The concept of group of functions, say βch(X,τ) preserving β-closed sets containing homeomorphism group h(X,τ) was studied by Arora,Tahiliani and Maki. In continuation to that, we study some new isomorphisms, mappings, subgroups and their properties.
