Properly colored and rainbow C4 ${C}_{4}$'s in edge‐colored graphs [PDF]
We present new sharp sufficient conditions for the existence of properly colored and rainbow (Formula presented.) 's in edge-colored graphs. Our first results deal with sharp color neighborhood conditions for the existence of properly colored (Formula ...

Representations of Edge Intersection Graphs of Paths in a Tree [PDF]
Let $\mathcal{P}$ be a collection of nontrivial simple paths in a tree $T$. The edge intersection graph of $\mathcal{P}$, denoted by EPT($\mathcal{P}$), has vertex set that corresponds to the members of $\mathcal{P}$, and two vertices are joined by an ...

Local edge coloring of graphs [PDF]
Let be a graph. A local edge coloring of G is a proper edge coloring such that for each subset S of E(G) with there exist edges such that where ns is the number of copies of P3 in the edge induced subgraph The maximum color assigned by a local edge coloring c to an edge of G is called the value of c and is denoted by The local edge chromatic number of ...

Edge‐colored complete graphs without properly colored even cycles: A full characterization [PDF]
The structure of edge-colored complete graphs containing no properly colored triangles has been characterized by Gallai back in the 1960s. More recently, Cǎda et al. and Fujita et al.

The Vertex-Rainbow Connection Number of Some Graph Operations
A path in an edge-colored (respectively vertex-colored) graph G is rainbow (respectively vertex-rainbow) if no two edges (respectively internal vertices) of the path are colored the same.

Edge Bundling Method Based on Homologous Control Points [PDF]
Edge bundling is an effective method to reduce the visual clutter caused by the visualization of the node-link diagram with a large number of complex connections.Generally,the edge bundling based on spatial proximity will lead to independent edge ...

Exploring Relationship Between Traditional Lattices and Graph Lattices of Topological Coding
It is known that there are no polynomial quantum algorithms to solve some lattice difficult problems. Uncolored graphic lattice and colored graphic lattice are the products of multidisciplinary intersection inspired by lattice theory. A uncolored graphic
