摘要：

At first a short discussion of the on/off boundary position dependence of the renormalization counter terms and beta-functions for generalized sigma-models on manifolds with boundary is given. Treating the energy-momentum tensor of such models as a two-dimensional distribution one can show that contrary to the first impression this does not imply any obstruction for the string interpretation of such models. The analysis is extended to the effect of dual loop corrections to string induced equations of motion, too.
