… The classical nano topological space is based on an equivalence relation on a set, but in
some situation, equivalence relations are nor suitable for coping with granularity, instead
the classical nano topology is extend to general binary relation based covering nano
topological space In this paper, we introduce some kernels, nano ∧r-set, nano ∧π-set,
nano λ-closed set and nano λπ-closed set in nano topological spaces and investigate some
of their properties. … Throughout this paper (U, τR(X)) (or X) represent nano topological …
