Tamagawa numbers of quasi-split groups over function fields
Ralf Köhl, M. M. Radhika, Ankit Rai
We use Morris' theory of Eisenstein series for reductive groups over global function fields in order to extend Harder's computation of Tamagawa numbers to quasi-split groups.

Lattices in $\R^n\rtimes\SL_2(\R)$
M. M. Radhika, Sandip Singh
We determine the existence of cocompact lattices in groups of the form $\V\rtimes\SL_2(\R)$, where $\V$ is a finite dimensional real representation of $\SL_2(\R)$. It turns out tha…

Singular Vectors on Manifolds over totally real Number Fields
Shreyasi Datta, M. M. Radhika
We extend the notion of singular vectors in the context of Diophantine approximation of real numbers with elements of a totally real number field . For , we establish a…
