We compactify the heterotic string to two dimensions.
It has been shown that BI type NLED may be arisen as a low energy limit of heterotic string theory [66, 68, 79-83], which led to an increased interest for BI type NLED theories.
Among the topics are elusive worldsheet instantons in heterotic string compactifications, the Witten equation and the geometry of the Landau-Ginzburg model, algebraic topological string theory, the fibrancy of symplectic homology in cotangent bundles, and the theory of higher rank stable pairs and virtual localization.
There are five already known string theories, i.e., [E.sub.8] x [E.sub.8] heterotic string, SO(32) heterotic string, SO(32) Type I string, Type IIA and Type IIB, each of them is an extreme theory of M-theory such as those shown in Fig.1.6.
