Interaction of Discrete States in TwoDimensional String Theory
Abstract
We study the couplings of discrete states that appear in the string theory embedded in two dimensions, and show that they are given by the structure constants of the group of area preserving diffeomorphisms. We propose an effective action for these states, which is itself invariant under this infinitedimensional group.
