Title: Strongly Cospectral Vertices in Trees

Affiliation: Universidade Federal de Minas Gerais, Brazil

Abstract: This talk is about the problem of finding a triple of pairwise strongly cospectral vertices at a tree. We present a construction of trees with cospectral non-similar vertices by looking at the limbs of the vertices. Then, we discuss the difficulties of finding such triples and comment about related problems.
