Following the discovery of spacetime anomaly cancellation in 1984 [1], string theory has
undergone rapid development in several directions. The early hope of making direct contact …

We apply the method of coadjoint orbits of W∞-algebra to the problem of non-relativistic
fermions in one dimension. This leads to a geometric formulation of the quantum theory in …

We use a recently proposed covariant procedure to reduce the Chern-Simons action of three-
dimensional higher-spin gravity to the boundary, resulting in a Lorentz covariant action for …

We discuss the basic features of the double scaling limit of the one dimensional matrix
model and its interpretation as a two dimensional string theory. Using-the collective field …

This thesis describes a new approach to conformal field theory. This approach combines the
method of coadjoint orbits with the algebraic structures of resolutions and chiral vertex …

Conditions for the construction of polynomial eigen-operators for the Hamiltonian of
collective string field theories are explored. Such eigen-operators arise for only one …

We rederive the w∞ Ward identities, starting from the existence of trivial linearized gauge
invariances, and using the method of canceled propagators in the operator formalism …

We construct composite operators in two-dimensional bosonized QCD, which obey a W∞
algebra, and discuss their relation to analogous objects recently obtained in the fermionic …
