On uniquely Hamiltonian claw-free and triangle-free graphs
A graph is uniquely Hamiltonian if it contains exactly one Hamiltonian cycle. In this note, we prove that claw-free graphs with minimum degree at least 3 are not uniquely Hamiltonian. We also show that this is best possible by exhibiting uniquely Hamiltonian claw-free graphs with minimum degree 2 and arbitrary maximum degree. Finally, we show that a construction due to Entringer and Swart can b...
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 $D>0$ ...
متن کاملDense triangle-free graphs are four-colorable: A solution to the Erdős-Simonovits problem
In 1972, Erdős and Simonovits [9] asked whether a triangle-free graph with minimum degree greater than n/3, where n is the number of vertices, has chromatic number at most three. Hajnal provided examples of triangle-free graphs with arbitrarily large chromatic number and minimum degree greater than (1/3− ε)n, for every ε > 0. Häggkvist [10] gave a counterexample to the Erdős-Simonovits problem ...
متن کاملDense graphs with small clique number
We consider the structure of Kr-free graphs with large minimum degree, and show that such graphs with minimum degree δ > (2r − 5)n/(2r − 3) are homomorphic to the join Kr−3 ∨ H where H is a triangle-free graph. In particular this allows us to generalize results from triangle-free graphs and show that Kr-free graphs with such minimum degree have chromatic number at most r+ 1. We also consider th...
متن کامل(5, 2)-Coloring of Sparse Graphs
We prove that every triangle-free graph whose subgraphs all have average degree less than 12/5 has a (5, 2)-coloring. This includes planar and projective-planar graphs with girth at least 12. Also, the degree result is sharp; we construct a minimal non(5, 2)-colorable triangle-free graph with 10 vertices that has average degree 12/5.
