Regular labelings and geometric structures
نویسنده
چکیده
Three types of geometric structure—grid triangulations, rectangular subdivisions, and orthogonal polyhedra— can each be described combinatorially by a regular labeling : an assignment of colors and orientations to the edges of an associated maximal or near-maximal planar graph. We briefly survey the connections and analogies between these three kinds of labelings, and their uses in designing efficient geometric algorithms.

Constructions of antimagic labelings for some families of regular graphs
In this paper we construct antimagic labelings of the regular complete multipartite graphs and we also extend the construction to some families of regular graphs.
متن کاملOn a dispersion problem in grid labeling
Given k labelings of a finite d-dimensional cubical grid, define the combined distance between two labels to be the sum of the l1-distance between the two labels in each labeling. We want to construct k labelings which maximize the minimum combined distance between any two labels. When d = 1, this can be interpreted as placing n non-attacking rooks in a k-dimensional chessboard of size n in suc...
متن کاملBalanced Degree-Magic Labelings of Complete Bipartite Graphs under Binary Operations
A graph is called supermagic if there is a labeling of edges where the edges are labeled with consecutive distinct positive integers such that the sum of the labels of all edges incident with any vertex is constant. A graph G is called degree-magic if there is a labeling of the edges by integers 1, 2, ..., |E(G)| such that the sum of the labels of the edges incident with any vertex v is equal t...
متن کاملOn the Number of Regular Edge Labelings
We prove that any irreducible triangulation on n vertices has O(4.6807) regular edge labelings and that there are irreducible triangulations on n vertices with Ω(3.0426) regular edge labelings. Our upper bound relies on a novel application of Shearer’s entropy lemma. As an example of the wider applicability of this technique, we also improve the upper bound on the number of 2-orientations of a ...
متن کاملSimply sequentially additive labelings of 2-regular graphs
We conjecture that any 2-regular simple graph has an SSA labeling. We provide several special cases to support our conjecture. Most of our constructions are based on Skolem sequences and on an extension of it. We establish a connection between simply sequentially additive labelings of 2-regular graphs and ordered graceful labelings of spiders.
