Abstract
We identify in some classes of unicyclic graphs (of fixed order and girth) those graphs whose index, i.e. the largest eigenvalue, is maximal. Besides, some (lower and upper) bounds on the indices of the graphs being considered are provided. © 2006 Elsevier Inc. All rights reserved.File in questo prodotto:
