Abstract: In this talk we introduce some of our recent results on Aα-spectra of graphs. We firstly characterize the connected graphs with only a few distinct Aα-eigenvalues. We secondly establish the relationship between the Aα-index and the independence number of graphs. We thirdly establish some spectral inequalities for connected (bipartite) graphs with maximum Aα-index. At last we characterize the graph determined by the generalized Aα-spectrum. This is a joint work with Wanting Sun.
