Spectral moments of trees with given degree sequence

Eric Ould Dadah Andriantiana, Stephan Wagner

Let ${\lambda }_1,\dots ,{\lambda }_n$ be the eigenvalues of a graph $G$. For any $k\ge 0$, the $k$-th spectral moment of $G$ is defined by $\M_k(G)=λ_1^k+\dots+λ_n^k$. We use the fact that $\M_k(G)…
