Regularization and quantization of higher dimensional current algebras
We present some recently discovered infinite dimensional Lie algebras that can be understood as extensions of the algebra Map(M, g) of maps from a compact p-dimensional manifold M to some finite
GRADED q-PSEUDO-DIFFERENTIAL OPERATORS AND SUPERSYMMETRIC ALGEBRAS
We give a supersymmetric generalization of the sine algebra and the quantum algebra Ut(sl(2)). Making use of the q-pseudo-differential operators graded with a fermionic algebra, we obtain a
On the Cohomology of the Lie Superalgebra of Contact Vector Fields on S 1|2
Abstract We investigate the first cohomology space associated with the embedding of the Lie superalgebra K(2) of contact vector fields on the (1,2)-dimensional supercircle S 1|2 in the Lie
A spinor-like representation of the contact superconformal algebra K′(4)
In this work we construct an embedding of a nontrivial central extension of the contact superconformal algebra K′(4) into the Lie superalgebra of pseudodifferential symbols on the supercircle S1/2.
Deforming the Lie Superalgebra of Contact Vector Fields on S1|1 Inside the Lie Superalgebra of Superpseudodifferential Operators on S1|1
Abstract We classify nontrivial deformations of the standard embedding of the Lie superalgebra K(1) of contact vector fields on the (1,1)-dimensional supercircle into the Lie superalgebra of
Schwinger terms and cohomology of pseudodifferential operators
We study the cohomology of the Schwinger term arising in second quantization of the class of observables belonging to the restricted general linear algebra. We prove that, for all pseudodifferential
Generalization of the algebra of the matrix pseudodifferential operators
We introduce the new nonhomogeneous graded matrix algebra Matn(R) over the ring R of the pseudodifferential operators of the arbitrary orders. This algebra forms the generalization of the algebra of
