  • Product Description

String theory is a promising candidate for a theory that unifies all the fundamental forces, including gravity, to a theory of everything. Heterotic string theories are in particular interesting since they naturally carry an exceptional gauge group that can be broken down to the standard model gauge group. These theories live in ten dimensions, where six of them constitute a so called Calabi-Yau space. Ultimately all the physical quantities, e.g. the spectrum, depend on the topology of this space and, if it is given as a sub-variety of a toric variety, these quantities can be derived by the cohomology of line bundles on the ambient space. Many such cohomology groups have to be calculated and, hence, the first part of this book is devoted to the development and the mathematical proof of a theorem that allows for a very efficient way to compute them. Furthermore applications and generalizations are presented. In the last chapter a duality between string models, called target space duality, is investigated in depth. A method to generate topologically distinct string models that all share the same physics is conjectured and supported by a large scan of over 80,000 geometries.
