The angular momentum-mass relation: a fundamental law from dwarf irregulars to massive spirals [PDF]
, 2018 In a $\Lambda$CDM Universe, the specific stellar angular momentum ($j_\ast$) and stellar mass ($M_\ast$) of a galaxy are correlated as a consequence of the scaling existing for dark matter haloes ($j_{\rm h}\propto M_{\rm h}^{2/3}$).

New fundamental relation of hyperrings
European Journal of Combinatorics, 2013 We prove that @q^* as previously defined [Int. J. Contemp. Math. Sci. 5 (2010) 721] is the smallest equivalence relation such that the quotient structure R/@q^* is a commutative fundamental ring. We also investigate some properties with respect to the commutative fundamental relation @q^* on a hyperring R.

Universal relation involving fundamental modes in two-fluid dark matter admixed neutron stars
European Physical Journal C: Particles and FieldsWe systematically investigate the fundamental oscillation frequencies of dark matter admixed neutron stars, focusing on models with self-interacting fermionic dark matter that couples to normal matter solely through gravity.

Boolean Rings Based On Multirings [PDF]
Journal of Sciences, Islamic Republic of Iran, 2021 The purpose of this paper is to construct Boolean rings from multirings. In this regards, a method to construct a multigroup(multiring) on a given non-empty set, are introduced and its properties has been investigated.

The Reducibility Concept in General Hyperrings
Mathematics, 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
Mathematics, 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,

A Survey on the Theory of n-Hypergroups
Mathematics, 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.

A Fundamental Relation between Supermassive Black Holes and Their Host Galaxies [PDF]
, 2000 The masses of supermassive black holes correlate almost perfectly with the velocity dispersions of their host bulges, Mbh ∝ σα, where α = 4.8 ± 0.5. The relation is much tighter than the relation between Mbh and bulge luminosity, with a scatter no larger

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 ...
