Synchronized Planarity with Applications to Constrained Planarity Problems

open access: yesACM Transactions on Algorithms, 2023
We introduce the problem S ynchronized P lanarity . Roughly speaking, its input is a loop-free multi-graph together with synchronization constraints that, e.g., match pairs of vertices of equal degree by providing a bijection between their edges. S ynchronized P

APPLICATION OF EQUIPMENT FOR AUTOMATIC CONTROL OF PLANAR STRUCTURES IN MANUFACTURING MASTER MASKS OF INTEGRATED CIRCUITS ON PHOTO-MASKS

open access: yesНаука и техника, 2007
Following the concept of defect-free manufacturing of master masks of IC on photo-masks, two Belarusian sets of optomechanical equipment for 0,3 5 p and 90 nanometers are presented in the paper. Each of the sets comprises:   • Multi-channel laser pattern

Planar Depth and Planar Subalgebras

open access: yesJournal of Functional Analysis, 2002
In [Planar algebras. I (preprint math.QA/9909027)] planar algebras were introduced by \textit{V. F. R. Jones} to get insight in the study of subfactors, especially in the algebraic-combinatorial aspects of the lattice of higher relative commutants. To each extremal type \(II_1\) finite index subfactor inclusion, Jones has associated a spherical \(C^*\)-

Recognizing IC-Planar and NIC-Planar Graphs

open access: yesJournal of Graph Algorithms and Applications, 2018
We prove that triangulated IC-planar graphs and triangulated $K_5$-free or $X4W$-free NIC-planar graphs can be recognized in cubic time. A graph is 1-planar if it can be drawn in the plane with at most one crossing per edge. A drawing is IC-planar if, in addition, each vertex is incident to at most one crossing edge and NIC-planar if two pairs of ...

Multilevel Planarity

open access: yesJournal of Graph Algorithms and Applications, 2018
In this paper, we introduce and study multilevel planarity, a generalization of upward planarity and level planarity. Let $G = (V, E)$ be a directed graph and let $\ell: V \to \mathcal P(\mathbb Z)$ be a function that assigns a finite set of integers to each vertex.

Clustered Planarity = Flat Clustered Planarity [PDF]

open access: yes, 2018
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.
