Asymmetric 2-colorings of Planar Graphs in S and S
نویسندگان
چکیده
We show that the edges of every 3-connected planar graph except K4 can be colored with two colors so that every embedding of the graph in S is asymmetric, and we characterize all planar graphs whose edges can be 2-colored so that every embedding of the graph in S is asymmetric.

Coloring with no 2-Colored P4's
A proper coloring of the vertices of a graph is called a star coloring if every two color classes induce a star forest. Star colorings are a strengthening of acyclic colorings, i.e., proper colorings in which every two color classes induce a forest. We show that every acyclic k-coloring can be refined to a star coloring with at most (2k2 − k) colors. Similarly, we prove that planar graphs have ...
متن کاملPerfect $2$-colorings of the Platonic graphs
In this paper, we enumerate the parameter matrices of all perfect $2$-colorings of the Platonic graphs consisting of the tetrahedral graph, the cubical graph, the octahedral graph, the dodecahedral graph, and the icosahedral graph.
متن کاملDefective List Colorings of Planar Graphs
We combine the concepts of list colorings of graphs with the concept of defective colorings of graphs and introduce the concept of defective list colorings. We apply these concepts to vertex colorings of various classes of planar graphs. A defective coloring with defect d is a coloring of the vertices such that each color class corresponds to an induced subgraph with maximum degree at most d. A...
متن کاملVertex-Coloring with Defects
Defective coloring is a variant of the traditional vertex-coloring in which adjacent vertices are allowed to have the same color, as long as the induced monochromatic components have a certain structure. Due to its important applications, as for example in the bipartisation of graphs, this type of coloring has been extensively studied, mainly with respect to the size, degree, diameter, and acyc...
متن کاملFine Structure of 4-Critical Triangle-Free Graphs II. Planar Triangle-Free Graphs with Two Precolored 4-Cycles
We study 3-coloring properties of triangle-free planar graphs $G$ with two precolored 4-cycles $C_1$ and $C_2$ that are far apart. We prove that either every precoloring of $C_1\cup C_2$ extends to a 3-coloring of $G$, or $G$ contains one of two special substructures which uniquely determine which 3-colorings of $C_1\ cup C_2$ extend. As a corollary, we prove that there exists a constant $D>0$ ...
