(k, p)-Planarity: A Relaxation of Hybrid Planarity [PDF]

open access: yesTheoretical Computer Science, 2018
We present a new model for hybrid planarity that relaxes existing hybrid representations. A graph $G = (V,E)$ is $(k,p)$-planar if $V$ can be partitioned into clusters of size at most $k$ such that $G$ admits a drawing where: (i) each cluster is associated with a closed, bounded planar region, called a cluster region; (ii) cluster regions are pairwise ...

Planar arcs [PDF]

open access: yesJournal of Combinatorial Theory, Series A, 2018
Let $p$ denote the characteristic of ${\mathbb F}_q$, the finite field with $q$ elements. We prove that if $q$ is odd then an arc of size $q+2-t$ in the projective plane over ${\mathbb F}_q$, which is not contained in a conic, is contained in the intersection of two curves, which do not share a common component, and have degree at most $t+p^{\lfloor ...

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

Practical challenges in data‐driven interpolation: Dealing with noise, enforcing stability, and computing realizations

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

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 \(C^*\)-

On the Genus of the Idempotent Graph of a Finite Commutative Ring

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
Let R be a finite commutative ring with identity. The idempotent graph of R is the simple undirected graph I(R) with vertex set, the set of all nontrivial idempotents of R and two distinct vertices x and y are adjacent if and only if xy = 0.
