Extremal quasi-unicyclic graphs with respect to the general multiplicative Zagreb indices

The general multiplicative Zagreb indices are modified versions of the famous Zagreb indices, which can help to predict the various activities and properties of organic compounds. In this article, the minimum and maximum general multiplicative Zagreb indices of quasi-unicyclic graphs with given order, with fixed number of pendant vertices and with perfect matchings are investigated. Furthermore, the corresponding extremal quasi-unicyclic graphs are identified.
