Local edge antimagic chromatic number of comb products involving path graph

Electronic Journal of Graph Theory and Applications
Let G = (V, E) be a graph with n vertices and no isolated vertices. A local edge antimagic labeling of G is a bijection f : V(G)→{1, 2, …, n} such that the weights of any two adjacent edges in G are distinct, where the weight of an edge in G is defined ...

On the partition dimension of comb product of path and complete graph [PDF]

AIP Conference Proceedings, 2017
For a vertex v of a connected graph G(V, E) with vertex set V(G), edge set E(G) and S ⊆ V(G). Given an ordered partition Π = {S1, S2, S3, …, Sk} of the vertex set V of G, the representation of a vertex v ∈ V with respect to Π is the vector r(v|Π) = (d(v, S1), d(v, S2), …, d(v, Sk)), where d(v, Sk) represents the distance between the vertex v and the ...

On the Rainbow and Strong Rainbow Coloring of Comb Product Graphs [PDF]

Acta Mechanica Slovaca, 2018
Let G=(V,E) be a simple, nontrivial, finite, connected and undirected graph. Let c be a coloring c: E(G)g{1,2,…,k}, kdN. A path of the edges of a colored graph is said to be a rainbow path if no two edges on the path have the same color but the adjacent edges may be colored by the same colors.

On metric chromatic number of comb product of ladder graph

Journal of Physics: Conference Series, 2021
Abstract All graphs in this paper are connected and nontrivial graph. Let f : V(G) → {1,2,…,k} be a vertex coloring of a graph G where two adjacent vertices may be colored the same color. Consider the color classes Π = {C1, C2,…, Ck}. For a vertex v of G, the representation color of v is the k-vektor r(v | Π) = {d(v, C1),d(v, C

Higher-point conformal blocks in the comb channel

Journal of High Energy Physics, 2020
We compute M -point conformal blocks with scalar external and exchange operators in the so-called comb configuration for any M in any dimension d. Our computation involves repeated use of the operator product expansion to increase the number of external ...

The matching book embedding under some graph operations

Electronic Journal of Graph Theory and Applications
The matching book embedding of a graph G is an embedding of G with the vertices on the spine, and each edge within a single page so that the edges on each page do not intersect and the degree of vertices on each page is at most one.

The strong 3-rainbow index of edge-comb product of a path and a connected graph

Electronic Journal of Graph Theory and Applications, 2022
Let G be a connected and edge-colored graph of order n, where adjacent edges may be colored the same. A tree in G is a rainbow tree if all of its edges have distinct colors. Let k be an integer with 2 ≤ k ≤ n.
