Title: | Some results on the index of unicyclic graphs | Journal: | Linear Algebra and Its Applications | Volume: | 416 | Issue: | 2-3 | First page: | 1048 | Last page: | 1059 | Issue Date: | 15-Jul-2006 | Rank: | M22 | ISSN: | 0024-3795 | DOI: | 10.1016/j.laa.2006.01.008 | 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. |
