On the automorphisms of numerical power monoids

Anwita Bhowmik, Salvatore Tringali

Let $H$ be a numerical monoid, that is, a cofinite submonoid of $N$ (the non-negative integers under addition). Denote by $P_{fin, 0} (H)$ the monoid obtained…

Divisible design graphs with selfloops

Anwita Bhowmik, Bart De Bruyn, Sergey Goryainov

We develop a basic theory for divisible design graphs with possible selfloops (LDDG's), and describe two infinite families of such graphs, some members of which are also classical…

Divisible design graphs from symplectic graphs over rings with precisely three ideals

Anwita Bhowmik, Sergey Goryainov

In this paper we construct two new infinite families of divisible design graphs based on symplectic graphs over rings with precisely three ideals.

Number of complete subgraphs of Peisert graphs and finite field hypergeometric functions

Anwita Bhowmik, Rupam Barman

For a prime $p \equiv 3 (mod 4)$ and a positive integer $t$ , let $q = p^{2 t}$ . Let $g$ be a primitive element of the finite field $F_{q}$ . The Peisert graph $P^{*} (q)$ is defi…
