# Recent Developments in String Theory: From Perturbative Dualities to M-Theory

@article{Haack1999RecentDI, title={Recent Developments in String Theory: From Perturbative Dualities to M-Theory}, author={Michael Haack and Boris Kors and Dieter Lust}, journal={arXiv: High Energy Physics - Theory}, year={1999} }

These lectures intend to give a pedagogical introduction into some of the developments in string theory during the last years. They include perturbative T-duality and non perturbative S- and U-dualities, their unavoidable demand for D-branes, an example of enhanced gauge symmetry at fixed points of the T-duality group, a review of classical solitonic solutions in general relativity, gauge theories and tendimensional supergravity, a discussion of their BPS nature, Polchinski's observations that…
