Chemical Trees with Extreme Values of a Few Types of Multiplicative Zagreb Indices
MATCH-COMMUNICATIONS IN MATHEMATICAL AND IN COMPUTER CHEMISTRY(2016)
摘要
We obtain sharp upper bounds for the second multiplicative Zagreb index and multiplicative sum Zagreb index and lower bound for the first multiplicative Zagreb index among the class of chemical trees. Also, we characterize those chemical trees achieving extremal values of multiplicative Zagreb indices that we considered.
