Abstract we derive the explicit action of the u-duality group of the stu model on both bps and non-bps extremal multi-center solutions as the class of known non-bps extremal solutions is not closed under u-duality, we generate in this way new solutions. Comments: 40 pages revtex and amslatex, 17 black&white eps figures v3: references added v4: details of the pinch singularity avoidance for the string quantization of the rindler space toy model have been added in both the body of the paper and in a new 7 page appendix other clarifications and references added this is the version accepted for publication in class.

Abstract we examine effects of the generalized uncertainty principle, predicted by various theories of quantum gravity to replace the heisenberg's uncertainty principle near the planck scale, on post inflation preheating in cosmology, and show that it can predict either an increase or a decrease in parametric resonance and a corresponding change in particle production. “fermions mixing and discrete symmetries”, ictp diploma thesis, ahmed farag ali, the abdus salam international center for theoretical physics (ictp), trieste, italy 2007 2.

This thesis covers in general two separate topics: the string effective actions and the geodesic motion of brane solutions the main theme of the first topic, ie, the string effective actions, is the construction of the abelian d-brane effective action in the limit of constant field strengths this action is known as the born-infeld action.

The fact that certain non-extremal black hole solutions obey unique first order equations has been known for some time in the literature, eg [8, 9, 11, 12], but the first order rewriting is imposed as an ansatz and does not exclude the existence of more general nonextremal solutions which cannot obtained this way.
