Heterotic Strings and CompactificationThe most pressing problem facing string theory is the question of breaking a 26- or 10-dimensional theory down to a realistic 4-dimensional theory. Until such a dimensional reduction can be made, the theory lacks any real contact with physically measurable quantities.

Calabi-Yau Spaces and OrbifoldsAlthough the heterotic string is a great advance over the usual formulation of string theory, the question still remains whether we can break the theory down to four dimensions and do rigorous phenomenology. The answer, unfortunately, is no.

Conformal Field Theory and Kac-Moody Algebras with anticommuting vectors, and the second is the GS model with genuine anticommuting spinors. Each formulation has its own distinct advantages and disadvantages. In this chapter, we will discuss the conformal field theory, which allows us to see the dynamic link between the two formalisms.

Light Cone Field Theoryklore that often seemed quite arbitrary. The choice of vertex functions, the measure of integration, the counting of diagrams, etc. all were inserted by hand. In summary, the first quantized theory suffers from several important defects:
