Harmonic Analysis Associated with the Generalized q-Bessel Operator [PDF]

open access: yesInternational Journal of Analysis and Applications, 2016
In this article, we give a new harmonic analysis associated with the generalized q-Bessel operator. We introduce the generalized $q$-Bessel transform, the generalized q-Bessel translation and the generalized $q$-Bessel convolution product.

Manifolds of Hilbert Space Projections. [PDF]

open access: yes, 2010
The Hardy space H2 () for the upper half-plane together with a multiplicative group of unimodular functions u() = exp(i(11 + ... +nn)), with n, gives rise to a manifold of orthogonal projections for the subspaces u() H2 () of L2 ().

Indefinite Hamiltonian systems whose Titchmarsh–Weyl coefficients have no finite generalized poles of non-positive type [PDF]

open access: yes, 2013
The two-dimensional Hamiltonian system (*)  y'(x)=zJH(x)y(x),  x∈(a,b), where the Hamiltonian H takes non-negative 2x2-matrices as values, and $J:= \begin{pmatrix} 0 & -1 \\ 1 & 0 \end{pmatrix}$, has attracted a lot of interest over the past decades ...

Quantum Mechanics and Quantum Field Theory: Algebraic and Geometric Approaches

open access: yesUniverse, 2023
This is a non-standard exposition of the main notions of quantum mechanics and quantum field theory, including recent results. It is based on the algebraic approach in which the starting point is a star-algebra and on the geometric approach in which the ...

Non-Markovian dynamics under time-translation symmetry

open access: yesPhysical Review Research, 2022
A dynamical symmetry is employed to determine the structure of the quantum non-Markovian time-local master equation. Such a structure is composed from two components: scalar kinetic coefficients and the standard quantum Markovian operator form.

Generalized variation and translation operator in some sequence spaces [PDF]

open access: yesHokkaido Mathematical Journal, 1988
Let X be the space of all real sequences. We consider two subsets X(\(\psi)\) and X(\(\phi\),\(\psi)\) defined by means of the sequential modulus and \(\phi\)-variation of sequences. Let \(X_{\zeta}\) be a modular space defined by a pseudomodular \(\zeta\) in X. Then \(\bar c=e_ 1\oplus e\) where \(e_ 1=(1,0,0,...)\) and \(e=(1,1,1,...)\), \(X^{\sim}_{\

Generalized frame operator, lower semiframes, and sequences of translates

open access: yesMathematische Nachrichten, 2023
AbstractGiven an arbitrary sequence of elements of a Hilbert space , the operator is defined as the operator associated to the sesquilinear form , for . This operator is in general different from the classical frame operator but possesses some remarkable properties. For instance, is always self‐adjoint with regard to a particular space, unconditionally
