Dendrimers are the unique chemical trees with maximum spectral radius
(Univ Kragujevac, 2012)It is shown that dendrimers have maximum spectral radius and maximum Collatz-Sinogowitz index among all chemical trees of given size. The result is also generalized for the class of chemical trees with prescribed number ... -
Semiregular trees with minimal Laplacian spectral radius
(Elsevier Inc, 2010-04-15)A semiregular tree is a tree where all non-pendant vertices have the same degree. Among all semiregular trees with fixed order and degree, a graph with minimal (adjacency/Laplacian) spectral radius is a caterpillar. Counter ...
