ABREU, Nair; LENES, Eber  and  ROJO, Oscar. The largest Laplacian and adjacency indices of complete caterpillars of fixed diameter. Proyecciones (Antofagasta) [online]. 2015, vol.34, n.2, pp.175-190. ISSN 0716-0917.

A complete caterpillar is a caterpillar in which each internal vertex is a quasi-pendent vertex. In this paper, in the class of all complete caterpillars on n vertices and diameter d, the caterpillar attaining the largest Laplacian index is determined. In addition, it is proved that this caterpillar also attains the largest adjacency index.

Keywords : Caterpillar; Laplacian matrix; Laplacian index; adjacency matrix; index; spectral radius.
