-shaped point set embeddings of high-degree plane graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
A point set embedding of a given plane graph on a given point set on a plane is a drawing of where each vertex is drawn on a point in . An orthogonal point set embedding of a plane graph is a point set embedding of such that each edge is drawn as a ...

The consecutively super edge-magic deficiency of graphs and related concepts

open access: yesElectronic Journal of Graph Theory and Applications, 2020
A bipartite graph G with partite sets X and Y is called consecutively super edge-magic if there exists a bijective function f : V(G) ⋃ E(G) → {1,2,...,|V(G)| + |E(G)|} with the property that f(X) = {1,2,...,|X|}, f(Y) = {|X|+1, |X|+2,...,|V(G)|} and f(u)+

Graph Abstraction and Abstract Graph Transformation [PDF]

open access: yes, 2007
Many important systems like concurrent heap-manipulating programs, communication networks, or distributed algorithms are hard to verify due to their inherent dynamics and unboundedness.

Insights into pegRNA design from editing of the cardiomyopathy‐associated phospholamban R14del mutation

open access: yesFEBS Letters, EarlyView.
This study reveals how prime editing guide RNA (pegRNA) secondary structure and reverse transcriptase template length affect prime editing efficiency in correcting the phospholamban R14del cardiomyopathy‐associated mutation. Insights support the design of structurally optimized enhanced pegRNAs for precise gene therapy.

Comparability graphs and intersection graphs

open access: yesDiscrete Mathematics, 1983
AbstractA function diagram (f-diagram) D consists of the family of curves {1̵ñ} obtained from n continuous functions fi:[0,1]→R(1⩽i⩽n). We call the intersection graph of D a function graph (f-graph). It is shown that a graph G is an f-graph if and only if its complement Ḡ is a comparability graph.

The Minimal Perimeter of a Log-Concave Function

open access: yesMathematics, 2020
Inspired by the equivalence between isoperimetric inequality and Sobolev inequality, we provide a new connection between geometry and analysis. We define the minimal perimeter of a log-concave function and establish a characteristic theorem of this ...

On sub-class sizes of mutually permutable products

open access: yesOpen Mathematics, 2021
In this paper, we investigate the influence of sub-class sizes on a mutually permutable factorized group in which the sub-class sizes of some elements of its factors have certain quantitative properties. Some criteria for a group to be pp-nilpotent or pp-

Graphs isomorphic to their path graphs [PDF]

open access: yesMathematica Bohemica, 2002
Summary: We prove that for every number \(n\geq 1\), the \(n\)-iterated \(P_3\)-path graph of \(G\) is isomorphic to \(G\) if and only if \(G\) is a collection of cycles, each of length at least 4. Hence, \(G\) is isomorphic to \(P_3(G)\) if and only if \(G\) is a collection of cycles, each of length at least 4.

The Determinant of Matching Matrix in the Evaluation of Matching Polynomial

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2011
A characterization is given for graphs whose matching polynomial is the determinant of their matching matrices. The matching matrix is then modified and its relation with other graph polynomials is examined.

Graph properties, graph limits and entropy [PDF]

open access: yes, 2013
We study the relation between the growth rate of a graph property and the entropy of the graph limits that arise from graphs with that property. In particular, for hereditary classes we obtain a new description of the colouring number, which by well ...
