On fixed points and stabilizers in solvable Baumslag--Solitar groups
Oorna Mitra, Ramya Nair
In this article, we study the fixed-point subgroups of the solvable Baumslag-Solitar groups $\BS(1,n)= \langle a, t \mid t a t^{-1} = a^{n} \rangle$, of automorphisms and end…

Twisted conjugacy in
Oorna Mitra, Mallika Roy, Enric Ventura
In this article, we solve the twisted conjugacy problem for solvable Baumslag--Solitar groups , i.e., we propose an algorithm which, given two elements a…

Embedding certain diffeomorphism groups into the quasi-isometry groups of Euclidean spaces
Oorna Mitra, Parameswaran Sankaran
We show that certain groups of diffeomorphisms and PL-homeomorphisms embed in the group of all quasi-isometries of the Euclidean spaces.
