The fundamental relation between electrohelicity and molecular optical activity [PDF]

open access: yes, 2023
Electrohelicity arises in molecules such as allene and spiropentadiene when their symmetry is reduced and helical frontier molecular orbitals (MOs) appear.

Cold-mode accretion : driving the fundamental mass-metallicity relation at z ∼ 2 [PDF]

open access: yes, 2016
We investigate the star formation rate (SFR) dependence on the stellar mass and gas-phase metallicity relation at z = 2 with MOSFIRE/Keck as part of the ZFIRE survey. We have identified 117 galaxies (1.98 10M(circle dot) yr(-1)) SFRs. At fixed mass, low

NEW FUNDAMENTAL RELATIONS IN HYPERRINGS AND THE CORRESPONDING QUOTIENT STRUCTURES [PDF]

open access: yesJournal of Algebraic Systems
‎‎In 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 ...

Superring of Polynomials over a Hyperring

open access: yesMathematics, 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.

Distances in spaces of physical models: partition functions versus spectra [PDF]

open access: yes, 2016
We study the relation between convergence of partition functions (seen as general Dirichlet series) and convergence of spectra and their multiplicities.

The Case for the Fundamental MBH-σ Relation

open access: yesFrontiers in Physics, 2020
Strong scaling relations between host galaxy properties (such as stellar mass, bulge mass, luminosity, effective radius etc) and their nuclear supermassive black hole's mass point toward a close co-evolution.

Gauss: The Last Entry [PDF]

open access: yes, 2016
We present one of the shortest examples of a statement with a visionary impact: we discuss an expectation by Gauss. His idea preludes developments only started more than a century later. Several proofs were given for the prediction by Gauss.

In Defence of Geometrical Algebra [PDF]

open access: yes, 2016
The geometrical algebra hypothesis was once the received interpretation of Greek mathematics. In recent decades, however, it has become anathema to many.

Relation Between Physical Abilities and Fundamental Motor Skills in Preschoolers

open access: yesPhysical Education Theory and Methodology, 2022
The aim of this study was to determine the interconnection between physical abilities and fundamental motor skills in preschool children. The aim was also to determine the differences in the observed variables in relation to gender.

Holomorphic modular forms and cocycles [PDF]

open access: yes, 2018
This is a slightly expanded version of my lecture at the conference Modular forms are everywhere at Bonn, May 2017, taking into account remarks by Don Zagier and Shaul ...
