We study a family of trees with degree k at all interior nodes and degree 1 at boundary nodes. The eigenvalues of the adjacency matrix have high multiplicities. As the trees grow, the graphs of those eigenvalues approach a piecewise‐constant “Cantor function.” For each value of , we will find the fraction of the eigenvalues that are given by .
