Relational Structures of Fundamental Theories [PDF]
Foundations 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.

Fundamental Relation Between Entropy Production and Heat Current [PDF]
Journal 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]
Mathematics 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 ...

Superring of Polynomials over a Hyperring
Mathematics, 2019 A Krasner hyperring (for short, a hyperring) is a generalization of a ring such that the addition is multivalued and the multiplication is as usual single valued and satisfies the usual ring properties.

NEW FUNDAMENTAL RELATIONS IN HYPERRINGS AND THE CORRESPONDING QUOTIENT STRUCTURES [PDF]
Journal of Algebraic SystemsIn this article, we introduce and analyze the smallest equivalence binary relation $\chi ^{*}$ on a hyperring $R$ such that the quotient $R/\chi ^{*}$, the set of all equivalence classes, is a commutative ring with identity and of ...

A fundamental relation between mass, SFR and metallicity in local and high redshift galaxies [PDF]
, 2010 We show that the mass-metallicity relation observed in the local universe is due to a more general relation between stellar mass M*, gas-phase metallicity and SFR.

The mass–metallicity and the fundamental metallicity relation revisited on a fully Te-based abundance scale for galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The relationships between stellar mass, gas-phase metallicity and star-formation rate (i.e. the mass–metallicity, MZR, and the fundamental metallicity relation, FMR) in the local Universe are revisited by fully anchoring the metallicity determination ...

A fundamental relation between the metallicity, gas content, and stellar mass of local galaxies [PDF]
, 2013 Recent results have suggested that the well known mass-metallicity relation has a strong dependence on the star formation rate, to the extent that a three dimensional ‘fundamental metallicity relation’ exists which links the three parameters with minimal

Fundamental relations in multialgebras. Applications
European Journal of Combinatorics, 2015 Based on the properties of the poset of those equivalence relations of a multialgebra for which the factor multialgebra is a universal algebra, we give a characterization for the fundamental relations of a multialgebra. We point out the benefits of our approach by giving two applications.

Fundamental metallicity relation in CALIFA, SDSS-IV MaNGA, and high-z galaxies [PDF]
Astronomy & Astrophysics, 2018 The metallicity of local galaxies is tightly related not only to stellar mass, i.e. the mass-metallicity relation, but also to the star formation rate (SFR) through the so-called fundamental metallicity relation (FMR); more active galaxies show lower ...
