Prediction of Radio-quiet Gamma-Ray Pulsar Distances Using the Fundamental Plane Relation

open access: greenThe Astrophysical Journal
The fundamental plane (FP) relation connects gamma-ray luminosity to intrinsic pulsar properties, offering the potential to estimate distances for radio-quiet (RQ) gamma-ray pulsars, where direct measurements are often unavailable. The Fermi Third Pulsar

The Reducibility Concept in General Hyperrings

open access: yesMathematics, 2021
By using three equivalence relations, we characterize the behaviour of the elements in a hypercompositional structure. With respect to a hyperoperation, some elements play specific roles: their hypercomposition with all the elements of the carrier set ...

Semihypergroup-Based Graph for Modeling International Spread of COVID-n in Social Systems

open access: yesMathematics, 2022
Graph theoretic techniques have been widely applied to model many types of links in social systems. Also, algebraic hypercompositional structure theory has demonstrated its systematic application in some problems. Influenced by these mathematical notions,

Relational Structures of Fundamental Theories [PDF]

open access: yesFoundations of Physics, 2021
General relativity and quantum mechanics have both revealed the relativity of certain notions that were previously thought to be absolute. I clarify the precise sense in which these theories are relational, and I argue that the various aspects of relationality pertain to the same movement in the progress of physical theories.

Strongly Regular Relations Derived from Fundamental Relation

open access: yesJournal of Algebraic Hyperstructures and Logical Algebras, 2023
We introduce a new regular relation δ on a given group G and show that δ is a congurence relation on G, with respect to module the commutator subgroup of G.

A Survey on the Theory of n-Hypergroups

open access: yesMathematics, 2023
This paper presents a series of important results from the theory of n-hypergroups. Connections with binary relations and with lattices are presented. Special attention is paid to the fundamental relation and to the commutative fundamental relation.

Auto-Engel Polygroups [PDF]

open access: yesMathematics Interdisciplinary Research, 2021
This paper introduces the concept of auto–Engel polygroups via the heart of hypergroups and investigates the relation between of auto–Engel polygroups and auto–nilpotent polygroups.

Fundamental Relation Between Entropy Production and Heat Current [PDF]

open access: yesJournal of statistical physics, 2018
We investigate the fundamental relation between entropy production rate and the speed of energy exchange between a system and baths in classical Markov processes.

Fundamental Functor Based on Hypergroups and Groups [PDF]

open access: yesMathematics Interdisciplinary Research, 2018
The purpose of this paper is to compute of fundamental relations of hypergroups. In this regards first we study some basic properties of fundamental relation of hypergroups, then we show that any given group is isomorphic to the fundamental group of a ...
