  Several mathematicians, including myself, have studied some unifications in
general topological spaces as well as in fuzzy topological spaces. For instance
in our earlier works, using operations on topological spaces, we have tried to
unify some concepts similar to continuity, openness, closedness of functions,
compactness, filter convergence, closedness of graphs, countable compactness
and Lindelof property. In this article, to obtain further unifications, we will
study $\phi_{1,2}$-compactness and relations between $\phi_{1,2}$-compactness,
filters and $\phi_{1,2}$% -closure operator.
