چکیده

‎let $g$ be a graph and $chi^{prime}_{aa}(g)$ denotes the minimum number of colors required for an‎ ‎acyclic edge coloring of $g$ in which no two adjacent vertices are incident to edges colored with the same set of colors‎. ‎we prove a general bound for $chi^{prime}_{aa}(gsquare h)$ for any two graphs $g$ and $h$‎. ‎we also determine‎ ‎exact value of this parameter for the cartesian product of two paths‎, ‎cartesian product of a path and a cycle‎, ‎cartesian product of two trees‎, ‎hypercubes‎. ‎we show that $chi^{prime}_{aa}(c_msquare c_n)$ is at most $6$ fo every $mgeq 3$ and $ngeq 3$‎. ‎moreover in some cases we find the exact value of $chi^{prime}_{aa}(c_msquare c_n)$‎.

Adjacent Vertex Distinguishing Acyclic Edge Coloring of the Cartesian Product of Graphs

Let G be a graph and χaa(G) denotes the minimum number of colors required for an acyclic edge coloring of G in which no two adjacent vertices are incident to edges colored with the same set of colors. We prove a general bound for χaa(G□H) for any two graphs G and H. We also determine exact value of this parameter for the Cartesian product of two paths, Cartesian product of a path and a cycle, C...

Adjacent vertex-distinguishing edge coloring of graphs

An adjacent vertex-distinguishing edge coloring, or avd-coloring, of a graph G is a proper edge coloring of G such that no pair of adjacent vertices meets the same set of colors. Let mad(G) and ∆(G) denote the maximum average degree and the maximum degree of a graph G, respectively. In this paper, we prove that every graph G with ∆(G) ≥ 5 and mad(G) < 3− 2 ∆ can be avd-colored with ∆(G) + 1 col...

Adjacent Vertex Distinguishing Incidence Coloring of the Cartesian Product of Some Graphs

All graphs in this paper are simple, connected and undirected. We use V (G) and E(G) to denote the set of vertices and the set of edges of a graph G, respectively. And we denote the maximum degree of G by ∆(G). The undefined terminology can be found in [1]. Let G be a graph of order n. For any vertex u ∈ V (G), N(u) denotes the set of all vertices adjacent to vertex u. Obviously, d(u) is equal ...

Edge-coloring Vertex-weightings of Graphs

Let $G=(V(G),E(G))$ be a simple, finite and undirected graph of order $n$. A $k$-vertex weightings of a graph $G$ is a mapping $w: V(G) to {1, ldots, k}$. A $k$-vertex weighting induces an edge labeling $f_w: E(G) to N$ such that $f_w(uv)=w(u)+w(v)$. Such a labeling is called an {it edge-coloring k-vertex weightings} if $f_{w}(e)not= f_{w}(echr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39'...

Adjacent Vertex Distinguishing Edge-Colorings

An adjacent vertex distinguishing edge-coloring of a simple graph G is a proper edge-coloring of G such that no pair of adjacent vertices meets the same set of colors. The minimum number of colors χa(G) required to give G an adjacent vertex distinguishing coloring is studied for graphs with no isolated edge. We prove χa(G) ≤ 5 for such graphs with maximum degree Δ(G) = 3 and prove χa(G) ≤ Δ(G) ...

Acyclic edge coloring of graphs

An acyclic edge coloring of a graph G is a proper edge coloring such that the subgraph induced by any two color classes is a linear forest (an acyclic graph with maximum degree at most two). The acyclic chromatic index χa(G) of a graph G is the least number of colors needed in any acyclic edge coloring of G. Fiamčík (1978) conjectured that χa(G) ≤ ∆(G) + 2, where ∆(G) is the maximum degree of G...
