Generalize Heisenberg Groups and Self-Duality [PDF]

open access: yesarXiv, 2016
This paper compares two generalizations of Heisenberg groups and studies their connection to one of the major open problems in the field of locally compact abelian groups, namely the description of the self-dual locally compact abelian groups ([12]). The first generalization is presented by the so called generalized Heisenberg groups $\mathbb{H}(\omega)

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Some remarks on K-lattices and the Adelic Heisenberg Group for CM curves

open access: yes, 2015
We define an adelic version of a CM elliptic curve $E$ which is equipped with an action of the profinite completion of the endomorphism ring of $E$. The adelic elliptic curve so obtained is provided with a natural embedding into the adelic Heisenberg ...

An integral formula on the Heisenberg group [PDF]

open access: yesAnnali di Matematica Pura ed Applicata, 2012
Let Hn denote the (2n + 1)-dimensional (sub-Riemannian) Heisenberg group. In this note, we shall prove an integral identity (see Theorem 1.2) which generalizes a formula obtained in the Seventies by Reilly. Some first applications will be given in Section 4.

An improved Hardy type inequality on Heisenberg group

open access: yesJournal of Inequalities and Applications, 2011
Motivated by the work of Ghoussoub and Moradifam, we prove some improved Hardy inequalities on the Heisenberg group ℍ n via Bessel function.

Decomposition of phase space and classification of Heisenberg groups [PDF]

open access: yesarXiv, 2008
Is every locally compact abelian group which admits a Heisenberg central extension isomorphic to the product of a locally compact abelian group and its Pontryagin dual? An affirmative answer is obtained for all the commonly occurring types of abelian groups having Heisenberg central extensions, including Lie groups and certain finite Cartesian products

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

D-tangent surfaces of timelike biharmonic D-helices according to Darboux frame on non-degenerate timelike surfaces in the Lorentzian Heisenberg group H

open access: yesBoletim da Sociedade Paranaense de Matemática, 2014
In this paper, we study D-tangent surfaces of timelike biharmonic D-helices according to Darboux frame on non-degenerate timelike surfaces in the Lorentzian Heisenberg group H.

Impact of Octahedral Aluminum Sites on Guest Molecule Adsorption in Zeolites: A Computational Study of 5‐Fluorouracil in Zeolite FAU

open access: yesChemistry – A European Journal, EarlyView.
Dispersion‐corrected density functional theory (DFT) calculations shed light on the interaction of the anticancer drug 5‐fluorouracil (5‐FU) with a framework‐associated octahedral aluminum site in a FAU‐type zeolite. The calculations help to explain the experimental observation of a limited 5‐FU release from zeolite samples containing such sites ...

Pedal curves of tangent surfaces of biharmonic b-general helices according to bishop frame in Heisenberg group Heis³

open access: yesBoletim da Sociedade Paranaense de Matemática, 2014
In this paper, we study pedal curves of tangent surfaces of biharmonic B-general helices according to Bishop frame in the Heisenberg group Heis³. We give necessary and sufficient conditions for B-general helices to be biharmonic according to Bishop frame.
