Fast 3-coloring Triangle-Free Planar Graphs
The first o(n2) algorithm for 3-coloring vertices of triangle-free planar graphs is shown, showing the time complexity of the algorithm is $\mathcal{O}(n\log n)$.
On Equivalent Color Transform and Four Coloring Theorem
A simple proof for four color theorem for planar graph is proposed based on ECT for a minimal $k-coloring of any graph G by removing redundant edges between any two vertices. Acyclically 3-colorable planar graphs • Mathematics J. Comb. Optim. • 2010 This paper shows that there exist infinite classes of cubic planar graphs that are not acyclically 3-colorable, and describes the series-parallel graphs for which every 3-coloring is acyClic and provides a linear-time recognition algorithm for such graphs. Approximating maximum integral multiflows on bounded genus graphs • Mathematics ICALP • 2021 We devise the first constant-factor approximation algorithm for finding an integral multi-commodity flow of maximum total value for instances where the supply graph together with the demand edges can Recent Excluded Minor Theorems We discuss splitter theorems for internally 4-connected graphs and for cyclically 5-connected cubic graphs, the graph minor theorem, link-less embeddings, Hadwiger's conjecture, Tutte's edge Non-Monochromatic and Conflict-Free Colorings on Tree Spaces and Planar Network Spaces • Mathematics Algorithmica • 2019 It is found that any set of n intervals in R 1 admits a non-monochromatic coloring with two colors and a conflict-free coloring with three colors, which generalizes to colorings of objects in more complex 1-dimensional spaces. Non-Monochromatic and Conflict-Free Coloring on Tree Spaces and Planar Network Spaces • Mathematics COCOON • 2018 This work investigates generalizations of any set of n intervals in $$\mathbb {R} ^1$$ admits a non-monochromatic coloring with two colors and a conflict-free coloring with three colors to colorings of objects in more complex 1-dimensional spaces, namely so-called tree spaces and planar network spaces. Disjoint Total Dominating Sets in Near-Triangulations • Mathematics ArXiv • 2022 We show that every simple planar near-triangulation with minimum degree at least three contains two disjoint total dominating sets. The class includes all simple planar triangulations other than the Coloring Eulerian Triangulations of the Klein Bottle • Mathematics Graphs Comb. • 2012 We show that an Eulerian triangulation of the Klein bottle has chromatic number equal to six if and only if it contains a complete graph of order six, and it is 5-colorable, otherwise. As a Triangle-Free Penny Graphs: Degeneracy, Choosability, and Edge Count We show that triangle-free penny graphs have degeneracy at most two, list coloring number (choosability) at most three, diameter$D=\Omega(\sqrt n)$, and at most$\min\bigl(2n-\Omega(\sqrt

Every Planar Graph Is 5-Choosable

Another proof is given, still using a computer, but simpler than Appel and Haken's in several respects, that every loopless planar graph admits a vertex-colouring with at most four different colours.

As has become standard, the four color map problem will be considered in the dual sense as the problem of whether the vertices of every planar graph (without loops) can be colored with at most four

Six-Rings in Minimal Five-Color Maps
Introduction. Kempe 1 and Heawood 2 have shown that five colors are sufficient for coloring any map on a sphere. We conjecture the existence of some maps for which five colors are necessary, and seek
