Some Properties of $ ast $-frames in Hilbert Modules Over Pro-C*-algebras [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2019
In this paper, by using the sequence of adjointable operators from pro-C*-algebra $ mathcal{A} $ into a Hilbert $ mathcal{A} $-module $ E $. We introduce frames with bounds in pro-C*-algebra $ mathcal{A} $.

Quantum Current Algebra in Action: Linearization, Integrability of Classical and Factorization of Quantum Nonlinear Dynamical Systems

open access: yesUniverse, 2022
This review is devoted to the universal algebraic and geometric properties of the non-relativistic quantum current algebra symmetry and to their representations subject to applications in describing geometrical and analytical properties of quantum and ...

The bulk Hilbert space of double scaled SYK

open access: yesJournal of High Energy Physics, 2022
The emergence of the bulk Hilbert space is a mysterious concept in holography. In [1], the SYK model was solved in the double scaling limit by summing chord diagrams.

Admissible Vectors and Hilbert Algebras [PDF]

open access: yesMediterranean Journal of Mathematics, 2021
Admissible vectors for unitary representations of locally compact groups are the basis for group-frame and covariant coherent state expansions. Main tools in the study of admissible vectors have been Plancherel and central integral decomposition, of applicability only under certain separability and semifiniteness restrictions. In this work we present a

Hilbert Space Fragmentation and Commutant Algebras

open access: yesPhysical Review X, 2022
We study the phenomenon of Hilbert space fragmentation in isolated Hamiltonian and Floquet quantum systems using the language of commutant algebras, the algebra of all operators that commute with each local term that appears in the Hamiltonian or each ...

BORDERED GE-ALGEBRAS [PDF]

open access: yesJournal of Algebraic Systems
The notions of (transitive, commutative, antisymmetric) bordered GE-algebras are introduced,and their properties are investigated. Relations between a commutative bordered GE-algebra and anantisymmetric bordered GE-algebra are considered, and also ...

A characterization of nonatomic Hilbert algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1978
We say that a Hilbert algebra is atomic if its fulfillment is generated by its minimal projections. We prove that Hilbert algebra A \mathcal {A}

BPS states meet generalized cohomology

open access: yesJournal of High Energy Physics, 2023
In this note we review a construction of a BPS Hilbert space in an effective supersymmetric quiver theory with 4 supercharges. We argue abstractly that this space contains elements of an equivariant generalized cohomology theory E G ∗ − $$ {E}_G^{\ast ...

Characterizations of Belligerent Interior GE-Filters in GE-Algebras

open access: yesPan-American Journal of Mathematics, 2023
The notion of GE-algebra is introduced by Bandaru et al. as a generalization of Hilbert algebra. The consept of interior GE-algebra is introduced by Lee et al., and related properties are investigated.
