Representation dimension of some finite groups

Gurleen Kaur, Amit Kulshrestha, Anupam Singh

For a finite group $G$ , the representation dimension is the smallest integer realizable as the degree of a complex faithful representation of $G$ . In this article, we compute repre…

Surjectivity of polynomial maps on Matrices

Saikat Panja, Prachi Saini, Anupam Singh

For $n \geq 2$ , we consider the map on $M_{n} (K)$ given by evaluation of a polynomial $f (X_{1}, \dots, X_{m})$ over the field $K$ . In this article, we explore the image o…

Powers in finite unitary groups

Saikat Panja, Anupam Singh

Let $U (n, F_{q^{2}})$ denote the subgroup of unitary matrices of the general linear group $GL (n, F_{q^{2}})$ which fixes a Hermitian form and $M \geq 2$ an…

Differential Central Simple Algebras

Parul Gupta, Yashpreet Kaur, Anupam Singh

Differential central simple algebras are the main object of study in this survey article. We recall some crucial notions such as differential subfields, differential splitting fiel…
