Abstract
Abstract In this paper, interesting properties of the generalized topological spaces, generated by the monotonic maps $$\sigma = (cl_{\delta }\circ int_{\delta }),$$ σ=(clδ∘intδ), $$\alpha = (int_{\delta }\circ cl_{\delta }\circ int_{\delta }),$$ α=(intδ∘clδ∘intδ), $$\pi = (int_{\delta }\circ cl_{\delta })$$ π=(intδ∘clδ) and $$\beta = (cl_{\delta }\circ int_{\delta }\circ cl_{\delta }),$$ β=(clδ∘intδ∘clδ), for any generalized topological space $$(X,g_{\delta })$$ (X,gδ) are deduced and analyzed. Special subfamilies of the family of monotonic maps $$\Gamma (X)$$ Γ(X) are studied and interesting results regarding generalized topologies are obtained.
