Welcome to my webpage.

On this page, I have posted publication only for the year 2014-2026, for a complete list of publications please see my attached CV, Section: Research Activities/Publications.
My Research Interest: Presently, I am interested to the Applications of topological category Theory to Convergence groups (probabilistic topological convergence groups; probabilistic convergence (topological) transformation groups - categorical aspects; probabilistic normed linear spaces; approach convergence groups; approach convergence transformation groups); Topological groups; Lattice-valued Topological Groups and Convergence Groups; Partial Metric Spaces and their applications to Computer Science; Quantale - Valued Partial Metric Spaces. Also, working on Monads and their Eilenberg-Moore categories in relation to the category of probabilistic convergence spaces; Approximation spaces and various closure operators.
