J ul 1 99 7 Deforming the Lie algebra of vector fields on S 1 inside the Poisson algebra on Ṫ ∗ S 1
We study deformations of the standard embedding of the Lie algebra Vect(S 1) of smooth vector fields on the circle, into the Lie algebra of functions on the cotangent bundle T * S 1 (with respect to the Poisson bracket). We consider two analogous but different problems: (a) formal deformations of the standard embedding of Vect(S 1) into the Lie algebra of functions on ˙ T * S 1 := T * S 1 \S 1 ...
متن کاملThe Lie Algebra of Smooth Sections of a T-bundle
In this article, we generalize the concept of the Lie algebra of vector fields to the set of smooth sections of a T-bundle which is by definition a canonical generalization of the concept of a tangent bundle. We define a Lie bracket multiplication on this set so that it becomes a Lie algebra. In the particular case of tangent bundles this Lie algebra coincides with the Lie algebra of vector fie...
متن کاملDeforming the Lie Superalgebra of Contact Vector Fields on S 1 | 1 inside the Lie Superalgebra of Superpseudodifferential operators on S 1 | 1
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 super-algebra of superpseudodifferential operators on the supercircle. This approach leads to the deformations of the central charge induced on K(1) by the canonical central extension of SΨDO.

15 صفحه اولOn dimensions of derived algebra and central factor of a Lie algebra
Some Lie algebra analogues of Schur's theorem and its converses are presented. As a result, it is shown that for a capable Lie algebra L we always have dim L=Z(L) 2(dim(L2))2. We also give give some examples sup- porting our results.
