Abstract

The equation of motion of the tachyon field is obtained by requiring conformal invariance of the closed bosonic string propagator in a tachyon background. The cubic tachyon coupling is also obtained in this way. These equations are generalizations of the Kosterlitz-Thouless flow equations and involve nonperturbative contributions to the functions.
