Toroidal Compactifications: 10-Dimensional Heterotic String,dditional sixteen dimensions are compactified on the weight-lattice of .or .. We then study D-branes on toroidal spaces and how they transform under T-duality. We introduce intersecting D-branes, their T-dual images and simple orientifolds on such toroidal spaces.

As such it is not a compendium of results but intended as textbook in the sense that most of the material is organized in

D. A. H. Murray,A. G. L. Wilsonroblem was the existence of a critical dimension, which is 26 for the bosonic string and 10 for the fermionic string. Another obstacle for the interpretation of string theory as a theory of strong interactions was the existence of a massless spin two particle which is not present in the hadronic world.

We close with an appendix on spinors in two dimensions. Quantisation of the fermionic string will be the subject of the following chapter.
