We find the general solution to Polchinski's classical scattering equations for (1+1)-dimensional string theory. This allows efficient computation of scattering amplitudes in the standard Liouville{times}{ital c}=1 background. Moreover, the solution leads to a mapping from a large class of time-dependent collective field theory backgrounds to corresponding nonlinear {sigma} models. Finally, we derive recursion relations between tachyon amplitudes. These may be summarized by an infinite set of… 
The first massive level of closed bosonic string theory is studied. Free-field equations are derived by imposing Weyl invariance on the worldsheet. A two-parameter solution to the equation of motion
The c = 1 string theory S-matrix revisited
A bstractWe revisit the perturbative S-matrix of c = 1 string theory from the worldsheet perspective. We clarify the origin of the leg pole factors, the non-analyticity of the string amplitudes, and
D-brane dynamics in the c = 1 matrix model
Recent work has shown that unstable D-branes in two-dimensional string theory are represented by eigenvalues in a dual matrix model. We elaborate on this proposal by showing how to systematically
On c=1 matrix model and 2D gravity - with emphasis on chiral formalism
In this thesis, we study the relationship between the effective spacetime the ory of Liouville string theory in two spacetime dimensions and the collective field of the c=1 matrix model by finding
Matrix model and time-like linear dilaton matter
We consider a matrix model description of the 2d string theory whose matter part is given by a time-like linear dilaton CFT. This is equivalent to the c = 1 matrix model with a deformed, but very

The covariant string field theory approach to open two-dimensional strings is developed, and the pole structure of the amplitudes becomes manifest, and their origin from the higher string modes becomes transparent.
c < 1 string from two dimensional black holes
We study a topological string description of the c < 1 non-critical string whose matter part is defined by the time-like linear dilaton CFT. We show that the topologically twisted N=2 SL(2,R)/U(1)


Classical limit of (1+1)-dimensional string theory
Excitations and interactions in d=1 string theory
We discuss the singlet sector of the d=1 matrix model in terms of a Dirac fermion formalism. The leading order two- and three-point functions of the density fluctuations are obtained by this method.

From loops to states in two-dimensional quantum gravity
From Loops to Fields in 2d Quantum Gravity
We discuss a target space field theory of macroscopic loops W(l,…) in two-dimensional gravity. The propagator and topology-changing amplitudes (string interactions) are considered as off-shell
Interaction of Tachyons and Discrete States in c=1 2-D Quantum Gravity
The two-dimensional (2-D) quantum gravity coupled to the conformal matter with $c=1$ is studied. We obtain all the three point couplings involving tachyons and/or discrete states via operator product
I study the Ward identities of the w∞ symmetry of the two-dimensional string theory. It is found that, not just an isolated vertex operator, but also a number of vertex operators colliding at a point
