Linear Algorithms for Partitioning Embedded Graphs of Bounded Genus

open access: yes, 1996
This paper develops new techniques for constructing separators for graphs embedded on surfaces of bounded genus. For any arbitrarily small positive " we show that any n-vertex graph G of genus g can be divided in O(n + g) time into components whose ...

The Crossing Number of The Hexagonal Graph H3,n

open access: yesDiscussiones Mathematicae Graph Theory, 2019
In [C. Thomassen, Tilings of the torus and the Klein bottle and vertex-transitive graphs on a fixed surface, Trans. Amer. Math. Soc. 323 (1991) 605–635], Thomassen described completely all (except finitely many) regular tilings of the torus S1 and the ...

The Thickness of Amalgamations and Cartesian Product of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
The thickness of a graph is the minimum number of planar spanning subgraphs into which the graph can be decomposed. It is a measurement of the closeness to the planarity of a graph, and it also has important applications to VLSI design, but it has been ...

List Edge Colourings of Some 1-Factorable Multigraphs

open access: yes, 1996
The List Edge Colouring Conjecture asserts that, given any multigraph G with chromatic index k and any set system fSe : e 2 E(G)g with each jSe j = k, we can choose elements se 2 Se such that se 6= sf whenever e and f are adjacent edges.

The Page Number Problem for Partially Ordered Sets

open access: yes, 2013
Umieszczenie grafu w książce jest definiowane przez kolejność jego wierzchołków na grzbiecie książki i przyporządkowanie jego krawędzi stronom książki tak, aby na żadnej stronie krawędzie nie przecinały się. Umieszczenie zbioru częściowo uporządkowanego (
