Parabosons, parafermions, and explicit representations of infinite-dimensional algebras [PDF]

open access: yes, 2010
The goal of this paper is to give an explicit construction of the Fock spaces of the parafermion and the paraboson algebra, for an infinite set of generators. This is equivalent to constructing certain unitary irreducible lowest weight representations of

Asymptotic States and S-Matrix Operator in de Sitter Ambient Space Formalism

open access: yesUniverse, 2023
Within the de Sitter ambient space framework, the two different bases of the one-particle Hilbert space of the de Sitter group algebra are presented for the scalar case.

Crystal isomorphisms in Fock spaces and Schensted correspondence in affine type A [PDF]

open access: yes, 2014
We are interested in the structure of the crystal graph of level $l$ Fock spaces representations of $\mathcal{U}_q (\widehat{\mathfrak{sl}_e})$. Since the work of Shan [26], we know that this graph encodes the modular branching rule for a corresponding ...

Symmetric Hilbert spaces arising from species of structures [PDF]

open access: yes, 2000
Symmetric Hilbert spaces such as the bosonic and the fermionic Fock spaces over some `one particle space' $\K$ are formed by certain symmetrization procedures performed on the full Fock space. We investigate alternative ways of symmetrization by building

Fourier transforms in generalized Fock spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
A classical Fock space consists of functions of the form,Φ↔(ϕ0,ϕ1,…,ϕq,…),where ϕ0∈C and ϕq∈L2(R3q), q≥1. We will replace the ϕq, q≥1 with q-symmetric rapid descent test functions within tempered distribution theory.

Hilbert spaces of symmetric analytical functions on $\ell_{1}$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
We consider completions of the space of symmetric polynomials on $\ell_{1}$ with respect to some Hilbert norm and investigate conditions under which the obtained spaces consist of analytic functions with domains in $\ell_{1}$.

Wavelet transforms in generalized Fock spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
A generalized Fock space is introduced as it was developed by Schmeelk [1-5], also Schmeelk and Takači [6-8]. The wavelet transform is then extended to this generalized Fock space.

Boundedness of the Segal-Bargmann Transform on Fractional Hermite-Sobolev Spaces

open access: yesJournal of Function Spaces, 2017
Let s∈R and 2≤p≤∞. We prove that the Segal-Bargmann transform B is a bounded operator from fractional Hermite-Sobolev spaces WHs,pRn to fractional Fock-Sobolev spaces FRs,p.

Solving the Bose-Hubbard model in new ways [PDF]

open access: yesQuantum, 2022
We introduce a new method for analysing the Bose-Hubbard model for an array of bosons with nearest neighbor interactions. It is based on a number-theoretic implementation of the creation and annihilation operators that constitute the model.
