On Dominating Energy in Bipolar Single-Valued Neutrosophic Graph [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
One of the most important concepts in graph theory for dealing with unpredictable phenomena is the concept of domination and it has gained attention from many scholars.

Neutrosophic Circular-arc Graphs and Proper circular-arc Graphs [PDF]

open access: yesNeutrosophic Sets and Systems
Graph theory is a fundamental branch of mathematics that studies networks made up of nodes (vertices) and connections (edges). A key concept in graph theory is the intersection graph, where vertices represent sets, and edges are drawn between vertices if

Minimal lambda-theories by ultraproducts [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
A longstanding open problem in lambda calculus is whether there exist continuous models of the untyped lambda calculus whose theory is exactly the least lambda-theory lambda-beta or the least sensible lambda-theory H (generated by equating all the ...

Using Multidimensional Matrices to Determine Graph Properties

open access: yesСовременные информационные технологии и IT-образование, 2022
The need to determine the most appropriate data model increases, as the complexity of the designed computing systems and computer networks increases. The graph model is one of the main models for this kind of tasks.

New heuristics for burning connected graphs [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2022
The concept of graph burning and burning number (bn(G)) of a graph G was introduced recently [4]. Graph burning models the spread of contagion (fire) in a graph in discrete time steps. bn(G) is the minimum time needed to burn a graph G. The problem is NP-

Relational Graph Models at Work [PDF]

open access: yesLogical Methods in Computer Science, 2018
We study the relational graph models that constitute a natural subclass of relational models of lambda-calculus. We prove that among the lambda-theories induced by such models there exists a minimal one, and that the corresponding relational graph model ...

Some new models for multiprocessor interconnection networks [PDF]

open access: yesYugoslav Journal of Operations Research, 2016
A multiprocessor system can be modeled by a graph G. The vertices of G correspond to processors while edges represent links between processors. To find suitable models for multiprocessor interconnection networks (briefly MINs), one can apply ...

On structures in hypergraphs of models of a theory

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
Hypergraphs of models of a theory are derived objects allowing toobtain an essential structural information about both giventheories and related semantic objects including graph ones.

The Concept of Dependency Game Tree Graphs as a Black Box in the Analysis of Automatic Transmissions

open access: yesTransport and Telecommunication, 2022
The methodology of graph theory has long had applications in mechanics. Graphs allow the simultaneous consideration and synthesis of the structure of a real system and the idealized structure of an equivalent model of a mechanical system.
