Abstract
|
The aim of this paper is to use correspondence between solutions in the c = 1 matrix model collective field theory and coupled dilaton-gravity to a massless scalar field. First, we obtain the incoming and outgoing fluctuations for the time-dependent backgrounds with the lightlike and spacelike boundaries. In the case of spacelike boundaries, we have done here for the first time. Then by using the leg-pole transformations we find the corresponding tachyon field in the two-dimensional string theory for the lightlikes and spacelikes boundary.
