    abstract     = {Summary: Let $G$ be a graph with vertex set $V(G)$ and edge set $E(G)$. The first and second multiplicative Zagreb indices of $G$ are $\Pi_1=\Pi_{x\in V(G)}\deg(x)^2$ and $\Pi_2=\Pi_{xy\in E(G)}\deg(x)\deg(y)$, respectively, where $\deg(v)$ is the degree of the vertex $v$. Let $\Cal T_n$ be the set of trees with $n$ vertices. We determine the elements of $\Cal T_n$, extremal w.r.t. $\Pi_1$ and $\Pi_2$.},
