Some Aspects of Open String Field Theories
Abstract
The construction of covariant string field theories is an important step toward a deeper understanding of string theories. This thesis discusses the general formulation of bosonic and supersymmetric covariant open string field theories and their second quantization. A particular emphasis is given to the perturbative calculation in the framework of string field theory. The use of string wave functional and the technique of conformal field theory are illustrated by explicit calculations of on- and off-shell string amplitudes. The background independent cubic actions for open strings are described briefly.
