https://doi.org/10.1007/978-3-476-05422-7This is a review of some basic features on the relation between su- pergravity and pure gauge theories with special emphasis on the relation between T-duality and supersymmetry. Some new results concerning the interplay between T-duality and near horizon geometries are presented.

https://doi.org/10.1007/978-3-7091-3636-2A review is made of some recent results in noncommutative geometry, including its use as a regularization procedure. Efforts to add a gravitational field to noncommutative models of space-time are also reviewed. Special emphasis is placed on the case which could be considered as the noncommutative analogue of a parallelizable space-time.

,Einiges über Kurvenwaben im Raum,The representation theory of a .-deformed Minkowski algebra, which is as quantum space a co-module of the .-Poincaré algebra, is studied. The spectra of the coordinates are discrete: space-time acquires a lattice-like structure. The eigenvalues grow exponentially and there are accumulation points on the light-cone.
