Structural balance and spectral properties of generalized corona product of signed graphs
Amrik Singh, Ravi Srivastava, Bibhas Adhikari +1
In this paper, we extend our earlier proposal of corona product of signed graphs into generalized corona product of signed graphs inspired by the generalized corona product of unsi…
A characterization of orthogonal permutative matrices of order 4
Amrita Mandal, Bibhas Adhikari
Orthogonal matrices which are linear combinations of permutation matrices have attracted enormous attention in quantum information and computation. In this paper, we provide a comp…
Seidel switching for weighted multi-digraphs and its quantum perspective
Supriyo Dutta, Bibhas Adhikari, Subhashish Banerjee
Construction of graphs with equal eigenvalues (co-spectral graphs) is an interesting problem in spectral graph theory. Seidel switching is a well-known method for generating co-spe…
