- W4301181326 abstract "A tree $T$, in an edge-colored graph $G$, is called {em a rainbow tree} if no two edges of $T$ are assigned the same color. For a vertex subset $Sin V(G)$, a tree that connects $S$ in $G$ is called an $S$-tree. A {em $k$-rainbow coloring} of $G$ is an edge coloring of $G$ having the property that for every set $S$ of $k$ vertices of $G$, there exists a rainbow $S$-tree $T$ in $G$. The minimum number of colors needed in a $k$-rainbow coloring of $G$ is the {em $k$-rainbow index of $G$}, denoted by $rx_k(G)$. In this paper, we obtain the exact values of $rx_3(K_{2,t})$ for any $tgeq 1$." @default.
