Magnetic fields in noncommutative quantum mechanics
Francois Delduc, Quentin Duret, Francois Gieres +1
We discuss various descriptions of a quantum particle on noncommutative space in a (possibly non-constant) magnetic field. We have tried to present the basic facts in a unified and…
Observables in Topological Theories: A Superspace Formulation
J. L. Boldo, C. P. Constantinidis, F. Gieres +2
Observables of topological Yang-Mills theory were defined by Witten as the classes of an equivariant cohomology. We propose to define them alternatively as the BRST cohomology clas…
Symmetries and observables in topological gravity
C. P. Constantinidis, A. Deandrea, F. Gieres +2
After a brief review of topological gravity, we present a superspace approach to this theory. This formulation allows us to recover in a natural manner various known results and to…
Topological Yang-Mills Theories and Their Observables: a Superspace Approach
Jose Luiz Boldo, Clisthenis P. Constantinidis, Francois Gieres +2
Witten's observables of topological Yang-Mills theory, defined as classes of an equivariant cohomology, are reobtained as the BRST cohomology classes of a superspace version of the…
Observables in Topological Yang-Mills Theories
Jose Luis Boldo, Clisthenis P. Constantinidis, Francois Gieres +2
Using topological Yang-Mills theory as example, we discuss the definition and determination of observables in topological field theories (of Witten-type) within the superspace form…
