Locality in GNS Representations of Deformation Quantization
In the framework of deformation quantization we apply the formal GNS construction to find representations of the deformed algebras in pre-Hilbert spaces over C[[λ]] and establish the notion of local operators in these pre-Hilbert spaces. The commutant within the local operators is used to distinguish ‘thermal’ from ‘pure’ representations. The computation of the local commutant is exemplified in...
متن کاملA Jordan GNS Construction for the Holonomy-Flux *-algebra
The holonomy-flux *-algebra was recently proposed as an algebra of basic kinematical observables for loop quantum gravity. We show the conventional GNS construction breaks down when the the holonomyflux *-algebra is allowed to be a Jordan algebra of observables. To remedy this, we give a Jordan GNS construction for the holonomy-flux *-algebra that is based on trace. This is accomplished by assu...
متن کاملSome remarks on the GNS representations of topological ∗ - algebras
After an appropriate restatement of the GNS construction for topological ∗-algebras we prove that there exists an isomorphism among the set Cycl(A) of weakly continuous strongly cyclic ∗-representations of a barreled dual-separable ∗-algebra with unit A, the space HilbA(A ∗) of the Hilbert spaces that are continuously embedded in A∗ and are ∗-invariant under the dual left regular action of A an...
متن کاملA Remark on the Deformation of GNS Representations of ∗ - Algebras
Motivated by deformation quantization we investigate the algebraic GNS construction of ∗representations of deformed ∗-algebras over ordered rings and compute their classical limit. The question if a GNS representation can be deformed leads to the deformation of positive linear functionals. Various physical examples from deformation quantization like the Bargmann-Fock and the Schrödinger represe...
متن کاملPharmacological studies of neutral saponins (GNS) of Panax Ginseng root.
Pharmacological studies of neutral saponins (GNS) of Panax Ginseng root, were performed. GNS showed CNS-depressant action in inhibition of spontaneous and exploratory movements, and in potentiation of CNS-depressant. A specific blocking action of conditioned response by GNS was significantly confirmed in small doses and did not produce loss of righting reflex, motor incoordination or myorelaxat...
