Some New Results on Lucky Labeling
Czerwi’nski et al. introduced Lucky labeling in 2009 and Akbari et al and A.Nellai Murugan et al studied it further. Czerwi’nski defined Lucky Number of graph as follows: A labeling of vertices of a graph G is called a Lucky labeling if for every pair ...

Uniform (Ck, Pk+1)-Factorizations of Kn − I When k Is Even
Let H be a connected subgraph of a graph G. An H-factor of G is a spanning subgraph of G whose components are isomorphic to H. Given a set H of mutually non-isomorphic graphs, a uniform H-factorization of G is a partition of the edges of G into H-factors

Shannon Entropy of Ramsey Graphs with up to Six Vertices
Shannon entropy quantifying bi-colored Ramsey complete graphs is introduced and calculated for complete graphs containing up to six vertices. Complete graphs in which vertices are connected with two types of links, labeled as α-links and β-links, are ...

Weak saturation numbers of and
A graph is weakly -saturated if contains no copy of , and there is an ordering of all edges of so that if they are added one at a time, they form a complete graph and each edge added creates a new copy of .

Complete bipartite graph is a totally irregular total graph
A graph G is called a totally irregular total k-graph if it has a totally irregular total k-labeling λ : V ∪ E→ 1, 2, ... , k, that is a total labeling such that for any pair of different vertices x and y of G, their weights wt(x) and wt(y) are distinct,

The 6-girth-thickness of the complete graph
The g-girth-thickness of a graph G is the minimum number of planar subgraphs of girth at least g whose union is G. In this paper, we determine the 6-girth-thickness of the complete graph Kn in almost all cases.

Detecting Matching Blunders of Multi-Source Remote Sensing Images via Graph Theory
Large radiometric and geometric distortion in multi-source images leads to fewer matching points with high matching blunder ratios, and global geometric relationship models between multi-sensor images are inexplicit.

A Note on the Geometry of Closed Loops
In this paper, we utilize the Ramsey theory to investigate the geometrical characteristics of closed contours. We begin by examining a set of six points arranged on a closed contour and connected as a complete graph. We assign the downward-pointing edges
