Planar and Quasi-Planar Simultaneous Geometric Embedding [PDF]
A simultaneous geometric embedding SGE of two planar graphs G 1 and G 2 with the same vertex set is a pair of straight-line planar drawings Γ1 of G 1 and Γ2 of G 2 such that each vertex is drawn at the same point in Γ1 and Γ2. Many papers have been devoted to the study of which pairs of graphs admit a SGE, and both positive and negative results have ...

Planar Depth and Planar Subalgebras
AbstractWe consider the notion of planar depth of a planar algebra, viz., the smallest n for which the planar algebra is generated by its ‘n-boxes’. We establish a simple result which yields a sufficient condition, in terms of the principal graph of the planar algebra, for the planar depth to be bounded by k. This suffices to determine the planar depth

On Another Class of Strongly Perfect Graphs
For a commutative ring R with unity, the associate ring graph, denoted by AG(R), is a simple graph with vertices as nonzero elements of R and two distinct vertices are adjacent if they are associates.

Finite planar emulators for K_{4,5} - 4K_2 and K_{1,2,2,2} and Fellows' Conjecture [PDF]
In 1988 Fellows conjectured that if a finite, connected graph admits a finite planar emulator, then it admits a finite planar cover. We construct a finite planar emulator for K_{4,5} - 4K_2.

Clustered Planarity = Flat Clustered Planarity [PDF]
The complexity of deciding whether a clustered graph admits a clustered planar drawing is a long-standing open problem in the graph drawing research area. Several research efforts focus on a restricted version of this problem where the hierarchy of the clusters is "flat", i.e., no cluster different from the root contains other clusters.

Exceptional planar polynomials [PDF]
Planar functions are special functions from a finite field to itself that give rise to finite projective planes and other combinatorial objects. We consider polynomials over a finite field $K$ that induce planar functions on infinitely many extensions of

An upward planar drawing of a directed graph (digraph) is a planar drawing such that all the edges are represented by curves monotonically increasing in the vertical direction. In this paper we introduce and study the concept of quasi-upward planarity.

Enumerating Hamiltonian Cycles in a Planar Graph Using Combinatorial Cycle Bases
Cycle bases belong to a k-connected simple graph used both for listing and enumerating Hamiltonian cycles contained in a planar graph. Planar cycle bases have a weighted induced graph whose weight values limited to 1.
