The Distance Between the Adjacency Spectral Center and the Characteristic Set of a Tree

Chaochao Zhu, Shipei Hu, Jingfu Huang +1

Let $\mathcal{S}(T)$ be the adjacency spectral center of a tree $T$, and let $\mathcal{C}(T)$ be its characteristic set. We determine the largest possible separation $d(T) := \operat…
