ON LOCAL IRREGULARITY OF THE VERTEX COLORING OF THE CORONA PRODUCT OF A TREE GRAPH [PDF]

open access: diamondUral Mathematical Journal, 2022
Let \(G=(V,E)\) be a graph with a vertex set \(V\) and an edge set \(E\). The graph \(G\) is said to be with a local irregular vertex coloring if there is a function \(f\) called a local irregularity vertex coloring with the properties: (i) \(l:(V(G ...

Vertex-Distinguishing IE-Total Colorings of Complete Bipartite Graphs Km,N(m < n) [PDF]

open access: bronzeDiscussiones Mathematicae Graph Theory, 2013
Let G be a simple graph. An IE-total coloring f of G is a coloring of the vertices and edges of G so that no two adjacent vertices receive the same color. Let C(u) be the set of colors of vertex u and edges incident to u under f. For an IE-total coloring

Strong parity vertex coloring of plane graphs [PDF]

open access: diamondDiscrete Mathematics & Theoretical Computer Science, 2014
A strong parity vertex coloring of a 2-connected plane graph is a coloring of the vertices such that every face is incident with zero or an odd number of vertices of each color.

Colorful Paths in Vertex Coloring of Graphs [PDF]

open access: diamondThe Electronic Journal of Combinatorics, 2011
A colorful path in a graph $G$ is a path with $\chi(G)$ vertices whose colors are different. A $v$-colorful path is such a path, starting from $v$. Let $G\neq C_7$ be a connected graph with maximum degree $\Delta(G)$. We show that there exists a $(\Delta(G)+1)$-coloring of $G$ with a $v$-colorful path for every $v\in V(G)$.

Hierarchical and modularly-minimal vertex colorings

open access: diamondThe Art of Discrete and Applied Mathematics, 2022
Cographs are exactly the hereditarily well-colored graphs, i.e., the graphs for which a greedy vertex coloring of every induced subgraph uses only the minimally necessary number of colors $χ(G)$. We show that greedy colorings are a special case of the more general hierarchical vertex colorings, which recently were introduced in phylogenetic ...

on Graceful Chromatic Number of Vertex amalgamation of Tree Graph Family

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2022
Proper vertex coloring c of a graph G is a graceful coloring if c is a graceful k-coloring for k∈{1,2,3,…}. Definition graceful k-coloring of a graph G=(V,E) is a proper vertex coloring c:V(G)→{1,2,…,k);k≥2, which induces a proper edge coloring c':E(G ...
