Let T-Delta(n) be the class of trees on n vertices whose all vertices, other than pendant ones, are of degree Delta (bidegreed trees). In this paper we consider some problems related to the index (largest eigenvalue) of bidegreed trees focusing our attention on those trees with small index. In particular, we identify those trees from T-Delta(n) whose index is minimal.

Abstract
Let T-Delta(n) be the class of trees on n vertices whose all vertices, other than pendant ones, are of degree Delta (bidegreed trees). In this paper we consider some problems related to the index (largest eigenvalue) of bidegreed trees focusing our attention on those trees with small index. In particular, we identify those trees from T-Delta(n) whose index is minimal.File in questo prodotto:
