Sign-balance of excedances over mod-k-alternating permutations and gamma-positivity
Hiranya Kishore Dey, Iswar Mahato
A permutation is called mod-k-alternating if its entries are restricted to having the same remainder as the index, modulo some integer In this paper, we find the sign-b…
Unimodality and peak location of the characteristic polynomials of two distance matrices of trees
Rakesh Jana, Iswar Mahato, Sivaramakrishnan Sivasubramanian
Unimodality of the normalized coefficients of the characteristic polynomial of distance matrices of trees are known and bounds on the location of its peak (the largest coefficient)…
A note on the distance and distance signless Laplacian spectral radius of complements of trees
Iswar Mahato, M. Rajesh Kannan
In this article, we show that the generalized tree shift operation increases the distance spectral radius, distance signless Laplacian spectral radius, and the -spectral radiu…
Minimizers for the energy of eccentricity matrices of trees
Iswar Mahato, M. Rajesh Kannan
The eccentricity matrix of a connected graph , denoted by , is obtained from the distance matrix of by keeping the largest nonzero entries in each row and ea…
