Topological rigidity of automorphism actions on nilmanifolds
Siddhartha Bhattacharya
Suppose are nilmanifolds and are automorphism actions of a discrete group on and respectively. We show that if and $(X_{2}, σ)…

Orbit equivalence and topological conjugacy of affine actions on compact abelian groups
Siddhartha Bhattacharya
In this paper we study topological rigidity of affine actions on compact connected metrizable abelian groups. We also classify one-parameter flows of translations upto orbit equiva…
