Abstract
The generalized Weierstrass representation for surfaces in R-3 is used to s tudy quantum effects for strings governed by Polyakov-Nambu-Goto action. Co rrelators of primary fields are calculated exactly in one-loop approximatio n for the pure extrinsic Polyakov action. Geometrical meaning of infrared s ingularity is discussed. The Nambu-Goto and spontaneous curvature actions a re treated perturbatively. (C) 1998 Elsevier Science B.V. All rights reserv ed.
