چکیده

We obtain an interesting realization of the de Rham cohomological operators of differential geometry in terms of the noncommutative q-superoscillators for the supersymmetric quantum group GLqp(1|1). In particular, we show that a unique quantum superalgebra, obeyed by the bilinears of fermionic and bosonic noncommutative q-(super)oscillators of GLqp(1|1), is exactly identical to that obeyed by the de Rham cohomological operators. A set of discrete symmetry transformations for a set of GLqp(1|1) covariant quantum superalgebras turns out to be the analogue of the Hodge duality ∗ operation of differential geometry. A connection with an extended Becchi-Rouet-Stora-Tyutin (BRST) algebra obeyed by the conserved and nilpotent (anti-)BRST and (anti-)co-BRST charges, the conserved ghost charge and a conserved bosonic charge (which is equal to the anticommutator of (anti-)BRST and (anti-)co-BRST charges) is also established. PACS numbers: 11.10.Nx; 03.65.-w; 04.60.-d; 02.20.-a

1 1 N ov 2 00 3 Noncommutative Geometry of Super - Jordanian OSp h ( 2 / 1 ) Covariant Quantum Space

Extending a recently proposed procedure of construction of various elements of differential geometry on noncommutative algebras, we obtain these structures on noncommu-tative superalgebras. As an example, a quantum superspace covariant under the action of super-Jordanian OSp h (2/1) is studied. It is shown that there exist a two-parameter family of torsionless connections, and the curvature com...

Symmetrizable Quantum Affine Superalgebras and Their Representations

Aspects of the algebraic structure and representation theory of the quantum affine superalgebras with symmetrizable Cartan matrices are studied. The irreducible integrable highest weight representations are classified, and shown to be deformations of their classical counterparts. It is also shown that Jimbo type quantum affine superalgebras can be obtained by deforming universal enveloping alge...

Algebraic generalization of quantum statistics

Generalized quantum statistics such as para-Bose and para-Fermi statistics are related to the basic classical Lie superalgebras B(0|n) and Bn. We give a quite general definition of “a generalized quantum statistics associated to a Lie superalgebra G”. This definition is closely related to a certain Z-grading of G. The generalized quantum statistics is determined by a set of root vectors (the cr...

ζ-function calculation of the Weyl determinant for two-dimensional non-abelian gauge theories in a curved background and its W-Z-W terms

Using a cohomological characterization of the consistent and the covariant Lorentz and gauge anomalies, derived from the complexification of the relevant algebras, we study in d = 2 the definition of the Weyl determinant for a non-abelian theory with Riemannian background. We obtain two second order operators that produce, by means of ζ-function regularization, respectively the consistent and t...
