Adjacency Spectra of Semigraphs
Pralhad M. Shinde
In this paper, we define the adjacency matrix of a semigraph. We give the conditions for a matrix to be semigraphical and give an algorithm to construct a semigraph from the semigr…

Algorithms in Linear Algebraic Groups
Sushil Bhunia, Ayan Mahalanobis, Pralhad Shinde +1
This paper presents some algorithms in linear algebraic groups. These algorithms solve the word problem and compute the spinor norm for orthogonal groups. This gives us an algorith…

Bilinear cryptography using finite -groups of nilpotency class 2
Ayan Mahalanobis, Pralhad Shinde
In this short note, we develop a novel idea of a bilinear cryptosystem using the discrete logarithm problem in matrices. These matrices come from a linear representation of a finit…
