چکیده

A supermanifold, Mm/n, can be caracterired by its smooth superfunctions which constitute an algebra A (Leites, Kostant). We associate canonically ~a Ia Gelfand, certain fibred manifolds on which the automorphisms (the Jordan automorphisms) of A actas diffeomorphisms. For example, the kernelsof all homomorphisms from the algebra of superfunctions onto the Grassmann algebra of dimension n form naturally a manifold of dimension m 2~1 if n is even. To be more specific we explain this and similar constructions in the case of the algebra of smooth exterior differential forms defined on a smooth manifold. This algebra defines a particular supermanifold Mm/rn.

A Proposal for a Differential Calculus in Quantum Mechanics

In this paper, using the Weyl-Wigner-Moyal formalism for quantum mechanics, we develop a quantum-deformed exterior calculus on the phase-space of an arbitrary hamiltonian system. Introducing additional bosonic and fermionic coordinates we construct a supermanifold which is closely related to the tangent and cotangent bundle over phase-space. Scalar functions on the super-manifold become equival...

Evolutionary Forms: the Generation of Differential-geometrical Structures. (symmetries and Conservation Laws.)

Evolutionary forms, as well as exterior forms, are skew-symmetric differential forms. But in contrast to the exterior forms, the basis of evolutionary forms is deforming manifolds (manifolds with unclosed metric forms). Such forms possess a peculiarity, namely, the closed inexact exterior forms are obtained from that. The closure conditions of inexact exterior form (vanishing the differentials ...

Cartan Calculus: Differential Geometry for Quantum Groups

The topic of this lecture is differential geometry on quantum groups. Several lecturers at this conference have talked about this subject. For a review and a fairly extensive list of references I would like to point the reader to the contributions of B. Jurco and S. L. Woronowicz in this proceedings. Here we shall propose a new rigid framework for the so-called Cartan calculus of Lie derivative...

2 00 6 On characteristic classes of Q - manifolds

We define the notion of characteristic classes for supermanifolds endowed with a homological vector field Q. These are valued in the cohomology of the Lie derivative operator L Q acting on arbitrary tensor fields. We formulate a classification theorem for intrinsic characteristic classes and give their explicit description. 1. Let M be a smooth supermanifold and T (M) = n,m∈N T (n,m) (M) be its...
