Representation Equivalence of Lattices in Lie Groups

Chandrasheel Bhagwat, Kaustabh Mondal

Let $I^_{1}$ and $I^_{2}$ be two lattices of finite covolume in a semisimple Lie group $G$ . We prove a spectral rigidity result for the representation spectra of the right regular repr…

A finite Linear Dependence of Discrete Series Multiplicities

Kaustabh Mondal, Gunja Sachdeva

Let $G$ be a connected semisimple simply connected Lie group with a compact Cartan subgroup and let $I^$ be a uniform lattice in $G$ . Let $G_{d}$ denote the set of equivale…

Chandrasheel Bhagwat, Kaustabh Mondal, Gunja Sachdeva

Let $(I ¨ , V_{I ¨} )$ be a finite dimensional representation of a maximal compact subgroup $K$ of a connected non-compact semisimple Lie group $G$ , and let $I^$ be a uniform torsion-fre…
