Abstract:
We show that almost all string theories, including the bosonic string, the superstring and -string theories, possess a twisted \nex2 superconformal symmetry. This enables us to establish a connection between topological gravity and the field theoretical description of matter coupled to gravity. We also show how the \brs operators of the -string can be obtained by hamiltonian reduction of . The tachyonic and ground ring states of -strings are described in the light of the \nex2 superconformal structure, and the ground ring generators for the non-critical -string are explicitly constructed. The relationship to models and quantum integrable systems is also briefly described.- string model: boson
