Eigenvalues and degree deviation in graphs
Vladimir Nikiforov
Given a graph G of order n and size m, let s(G)= sum|d(u)-2m/n|, where the sum is taken over all vertices u of G. We investigate upper and lower bounds on eigenvalues of G in terms…

Walks and the spectral radius of graphs
Vladimir Nikiforov
We give upper and lower bounds on the spectral radius of a graph in terms of the number of walks. We generalize a number of known results.
