Nets of algebras for generally covariant QFT — •Martin Rainer — Kosmologie, Inst. für Mathematik, Univ. Potsdam, PF 601553, D-14415 Potsdam

A possibity to formulate a QFT on differentiable manifolds in a generally covariant manner based on nets of C^*-algebras is investigated. In particular one may implement IR and UV cutoffs algebraically, thus avoiding the usual conflict with general covariance.
