Symmetry Representations in the Rigged Hilbert Space Formulation of Quantum Mechanics [PDF]

open access: yes, 2002
We discuss some basic properties of Lie group representations in rigged Hilbert spaces. In particular, we show that a differentiable representation in a rigged Hilbert space may be obtained as the projective limit of a family of continuous ...

Super Hilbert Spaces [PDF]

open access: yesCommunications in Mathematical Physics, 2000
The basic mathematical framework for super Hilbert spaces over a Grassmann algebra with a Grassmann number-valued inner product is formulated. Super Hilbert spaces over infinitely generated Grassmann algebras arise in the functional Schroedinger representation of spinor quantum field theory in a natural way.

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

Beyond gauge theory: Hilbert space positivity and causal localization in the presence of vector mesons [PDF]

open access: yes, 2016
The Hilbert space formulation of interacting $s=1$ vector-potentials stands in an interesting contrast with the point-local Krein space setting of gauge theory.

Hilbert spaces induced by Hilbert space valued functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1983
Let E E be an arbitrary set and F ( E ) \mathcal {F}(E) a linear space composed of all complex valued functions on E E . Let H \mathcal {H} be a (possibly finite-dimensional) Hilbert space with inner product (

The Characterization and Stability of g-Riesz Frames for Super Hilbert Space

open access: yesJournal of Function Spaces, 2015
G-frames and g-Riesz frames as generalized frames in Hilbert spaces have been studied by many authors in recent years. The super Hilbert space has a certain advantage compared with the Hilbert space in the field of studying quantum mechanics.

Flows in Infinite-Dimensional Phase Space Equipped with a Finitely-Additive Invariant Measure

open access: yesMathematics, 2023
Finitely-additive measures invariant to the action of some groups on a separable infinitedimensional real Hilbert space are constructed. The invariantness of a measure is studied with respect to the group of shifts on a vector of Hilbert space, the ...

Reproducing Kernel Hilbert Space vs. Frame Estimates

open access: yesMathematics, 2015
We consider conditions on a given system F of vectors in Hilbert space H, forming a frame, which turn H into a reproducing kernel Hilbert space. It is assumed that the vectors in F are functions on some set Ω .

The space of twisted cubics [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2021
We consider the Cohen-Macaulay compactification of the space of twisted cubics in projective n-space. This compactification is the fine moduli scheme representing the functor of CM-curves with Hilbert polynomial 3t+1. We show that the moduli scheme of CM-

Wormholes as Basis for the Hilbert Space in Lorentzian Gravity [PDF]

open access: yes, 1994
We carry out to completion the quantization of a Friedmann-Robertson-Walker model provided with a conformal scalar field, and of a Kantowski-Sachs spacetime minimally coupled to a massless scalar field.
