On the first variable Zagreb index

2017
Summary: The first variable Zagreb index of graph \(G\) is defined as \(M_1^\lambda(G)=\sum_{x\in V(G)}d(v)^{2\lambda}\), where \(\lambda\) is a real number and \(d(v)\) is the degree of vertex \(v\). In this paper, some upper and lower bounds for the distribution function and expected value of this index in random increasing trees (recursive trees ...
