| Summary: | We present a review of the basics of supermanifold theory
(in the sense of Berezin-Kostant-Leites-Manin) from a physicist's
point of view. By considering a detailed example of what does it mean
the expression “to integrate an ordinary superdifferential equation”
we show how the appearance of anticommuting parameters playing the
role of time is very natural in this context. We conclude that in
dynamical theories formulated whithin the category of supermanifolds,
the space that classically parametrizes time (the real line ℝ)
must be replaced by the simplest linear supermanifold ℝ1|1.
This supermanifold admits several different Lie supergroup structures, and we
analyze from a group-theoretic point of view what is the meaning of the usual
covariant superderivatives, relating them to a change in the underlying group law. This result is extended to the case of N-supersymmetry. |
