Combinatorial maps
The classical approach to maps, as surveyed by Coxeter and Moser (“Generators and Relations for Discrete Groups,” Springer-Verlag, 1980), is by cell decomposition of a surface. A more recent approach, by way of graph embedding schemes, is taken by Edmonds (Notices Amer. Math. Sot. 7 (1960), 646), Tutte (Canad. J. Math. 31 (5) (1979), 986-1004), and others. Our intention is to formulate a purely...
متن کاملCubic Pisot unit combinatorial games
Generalized Tribonacci morphisms are defined on a three letters alphabet and generate the so-called generalized Tribonacci words. We present a family of combinatorial removal games on three piles of tokens whose set of P-positions is coded exactly by these generalized Tribonacci words. To obtain this result, we study combinatorial properties of these words like gaps between consecutive identica...
متن کاملGray coding cubic planar maps
The idea of (combinatorial) Gray codes is to list objects in question in such a way that two successive objects differ in some pre-specified small way. In this paper, we utilize β-description trees to cyclicly Gray code three classes of cubic planar maps, namely, bicubic planar maps, 3-connected cubic planar maps, and cubic non-separable planar maps.

متن کاملIntroduction to Combinatorial Maps
Preface Maps as a mathematical main topic arose probably from the four color problem[Ore1] and the more general map coloring problem[Rin1] in the mid of the nineteenth century. I could not list even main references on them because it is well known for mathematicians and beyond the scope of this lecture notes. Here, I only intend to present a comprehensive theory of combinatorial maps as a rigor...
