Dilating Covariant Representations of the Non-commutative Disc Algebras
Let φ be an isometric automorphism of the non-commutative disc algebra An for n ≥ 2. We show that every contractive covariant representation of (An, φ) dilates to a unitary covariant representation of (On, φ). Hence the C*-envelope of the semicrossed product An ×φ Z is On ×φ Z.
متن کاملD-branes and the Non-commutative Structure of Quantum Spacetime
A worldsheet approach to the study of non-abelian D-particle dynamics is presented based on viewing matrix-valued D-brane coordinate fields as coupling constants of a deformed σ-model which defines a logarithmic conformal field theory. The shortdistance structure of spacetime is shown to be naturally captured by the Zamolodchikov metric on the corresponding moduli space which encodes the geomet...
متن کاملRelativistic Spinning Particle and a New Non-commutative Spacetime
The relativistic spinning particle model, recently proposed by Staruszkiewicz, is analyzed in a Hamiltonian framework. The model is heavily constrained and constraint analysis, in the Dirac scheme, is both novel and instructive. Our major finding is an associated noncommutative spacetime the structure of which is completely new. We have shown that this non-commutative phase space algebra is ess...
متن کاملA non-commutative Minkowskian spacetime from a quantum AdS algebra
A quantum deformation of the conformal algebra of the Minkowskian spacetime in (3 + 1) dimensions is identified with a deformation of the (4 + 1)-dimensional AdS algebra. Both Minkowskian and AdS first-order non-commutative spaces are explicitly obtained, and the former coincides with the well known κ-Minkowski space. Next, by working in the conformal basis, a new non-commutative Minkowskian sp...
متن کاملCovariant Forms of Lax One-fieldoperators: from Abelian to Non-commutative
Polynomials in differentiation operators are considered. Joint covariance with respect to Darboux transformations of a pair of such polynomials (Lax pair) as a function of one-field is studied. Methodically, the transforms of the coefficients are equalized to Frechèt differential (first term of the Taylor series on prolonged space) to establish the operator forms. In the commutative (Abelian) c...
