Span of a Graph: Keeping the Safety Distance [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
Inspired by Lelek's idea from [Disjoint mappings and the span of spaces, Fund. Math. 55 (1964), 199 -- 214], we introduce the novel notion of the span of graphs.

Evaluation of the effects of chlorhexidine digluconate with and without cBD103 or cCath against multidrug‐resistant clinical isolates of Staphylococcus pseudintermedius

open access: yesVeterinary Dermatology, Volume 33, Issue 1, Page 17-e6, February 2022., 2022
Background – Because of the increased incidence of multidrug‐resistant (MDR) bacteria, the use of disinfectants over antibiotics has been encouraged. However, the interactions between disinfectants and host local immunity are poorly understood. Objective – To assess the effects of chlorhexidine digluconate (Chx), with and without selected host defence ...

Correlations in totally symmetric self‐complementary plane partitions

open access: yesTransactions of the London Mathematical Society, Volume 8, Issue 1, Page 493-526, December 2021., 2021
Abstract Totally symmetric self‐complementary plane partitions (TSSCPPs) are boxed plane partitions with the maximum possible symmetry. We use the well‐known representation of TSSCPPs as a dimer model on a honeycomb graph enclosed in 1/12 of a hexagon with free boundary to express them as perfect matchings of a family of non‐bipartite planar graphs ...

Computational and topological properties of neural networks by means of graph-theoretic parameters

open access: yesAlexandria Engineering Journal, 2023
A neural network is a computer system modeled on the nerve tissue and nervous system. In this sense, neural networks refer to systems of neurons, either organic or artificial in nature.

On vertex PI index of certain triangular tessellation networks

open access: yesMain Group Metal Chemistry, 2021
The Wiener index, due to its many applications is considered to be one of very important distance-based index. But the Padmaker-Ivan (PI) index is kind of the only distance related index linked to parallelism of edges.

The Compared Costs of Domination Location-Domination and Identification

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let G = (V, E) be a finite graph and r ≥ 1 be an integer. For v ∈ V, let Br(v) = {x ∈ V : d(v, x) ≤ r} be the ball of radius r centered at v. A set C ⊆ V is an r-dominating code if for all v ∈ V, we have Br(v) ∩ C ≠ ∅; it is an r-locating-dominating code

Under which conditions is λ″(G)=κ″(L(G))?

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
In this paper we show that if G is a connected graph such that [Formula: see text], [Formula: see text] and [Formula: see text] then [Formula: see text] exists and [Formula: see text] if and only if G is not super-[Formula: see text]. We also obtain some

Axioms for consensus functions on the n-cube [PDF]

open access: yes, 2016
An elementary general result is proved that allows for simple characterizations of well-known location/consensus functions (median, mean and center) on the n-cube.

Power Domination in the Generalized Petersen Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
The problem of monitoring an electric power system by placing as few measurement devices in the system can be formulated as a power dominating set problem in graph theory.

On the Two-Dimensional Version of the Sperner Lemma and Brouwer’s Theorem

open access: yesAnnales Mathematicae Silesianae, 2022
In this work the Brouwer fixed point theorem for a triangle was proved by two methods based on the Sperner Lemma. One of the two proofs of Sperner’s Lemma given in the paper was carried out using the so-called index.
