Let $r,k$ be natural number. By a proper $k$-coloring of a graph $G$, we mean a map $c : V (G) \rightarrow S$, where $|S| = k$, such that any two adjacent vertices receive different colors. An $r$-dynamic $k$-coloring is a proper $k$-coloring $c$ of $G$ such that $|c(N (v))| \geq min\{r, d(v)\}$ for each vertex $v$ in $V (G)$, where $N (v)$ is the neighborhood of $v$ and $c(S) = \{c(v) : v \in S\}$ for a vertex subset $S$ . The $r$-dynamic chromatic number, written as $\chi_r(G)$, is the minimum $k$ such that $G$ has an $r$-dynamic $k$-coloring. In this paper, we will show some exact values of $\chi_r(G)$ when $G$ is an operation of special graphs. dc.description.sponsorship CGANT UNEJ en_US dc.language.iso id en_US dc.subject r-dynamic coloring, chromatic number, shackle, graph operations en_US dc.title The r-Dynamic Chromatic Number of Special Graph Operations en_US dc.type Working Paper en_US
