Abstract
We derive the smodel tachyon ßfunction equation of 2dimensional string theory, in the background of flat space and linear dilaton, working entirely within the c = 1 matrix model. The tachyon β function equation is satisfied by a nonlocal and nonlinear combination of the (massless) scalar field of the matrix model. We discuss the possibility of describing the 'discrete states' as well as other possible gravitational and higher tensor backgrounds of 2dimensional string theory within the c = 1 matrix model. We also comment on the realization of the Winfinity symmetry of the matrix model in the string theory. The present work reinforces the viewpoint that a nonlocal (and nonlinear) transform is required to extract the spacetime physics of 2dimensional string theory from the c = 1 matrix model.
