Characterization of Erdös matrices by their zero entries

Priyanka Karmakar, Hariram Krishna, Souvik Pal +1

An Erdös matrix $E$ is a bistochastic matrix whose sum of squares of entries (Frobenius norm squared) equals its maxtrace (maximum of all the $σ$ -traces for permutations $σ$ 's). We…

Bounds for the Bergman kernel and the sup-norm of holomorphic Siegel cusp forms

Soumya Das, Hariram Krishna

We prove `polynomial in $k$ ' bounds on the size of the Bergman kernel for the space of holomorphic Siegel cusp forms of degree $n$ and weight $k$ . When $n = 1, 2$ our bounds agree wit…
