Pointwise dynamics under Orbital Convergence
Abdul Gaffar Khan, Pramod Kumar Das, Tarun Das
We obtain sufficient conditions under which the limit of a sequence of functions exhibits a particular dynamical behaviour at a point like expansivity, shadowing, mixing, sensitivi…

Topologically Stable Equicontinuous Non-Autonomous Systems
Abdul Gaffar Khan, Pramod Kumar Das, Tarun Das
We find sufficient conditions for commutative non-autonomous systems on certain metric spaces to be topologically stable. In particular, we prove that (i) Every mean equicontinuous…

Specification for Group Actions on Uniform Spaces
Abdul Gaffar Khan, Pramod Kumar Das, Tarun Das
We extend specification and periodic specification to finitely generated group actions on uniform spaces using a concept of specification point. We prove that certain group actions…
