Abstract (EN): We discuss the interplay between field redefinition ambiguities at orders alpha' and alpha' 2 in the gravitational sector of closed string theory effective actions for the actions for the case of a non-constant dilaton field. We show that, as a consequence, apparently different effective actions for this sector existing in the literature are, in fact, equivalent and discuss the implications of our results for the conjectured relationship between sigma-model beta-functions and string equations of motion.
