On non-surjective word maps on
Arindam Biswas, Jyoti Prakash Saha
Jambor--Liebeck--O'Brien showed that there exist non-proper-power word maps which are not surjective on for infinitely many . This provided th…
Spectrum of twists of Cayley and Cayley sum graphs
Arindam Biswas, Jyoti Prakash Saha
Let be a finite group with and be a subset of . Given an automorphism of , the twisted Cayley graph (resp. the twisted Cayley sum graph $C…
Asymptotic behaviour of minimal complements
Arindam Biswas, Jyoti Prakash Saha
The notion of minimal complements was introduced by Nathanson in 2011 as a natural group-theoretic analogue of the metric concept of nets. Given two non-empty subsets in a g…
A Cheeger type inequality in finite Cayley sum graphs
Arindam Biswas, Jyoti Prakash Saha
Let be a finite group and be a symmetric generating set of with . We show that if the undirected Cayley sum graph is an expander graph and is non-bi…

On Frobenius semisimplicity in Hida families
Jyoti Prakash Saha
Let be a prime and be a prime not dividing the tame level of a -ordinary Hida family. We prove that the actions of the Frobenius element at on the…
