Phys. Rev. D 37, 1083–1085 (1988)Critical dimension of strings with an extrinsic curvatureReceived 11 March 1987; published in the issue dated 15 February 1988 The conformal anomaly is calculated by using the path-integral method to determine the critical dimension for a string theory with an extrinsic curvature by appropriately defining the first-order form of this Lagrangian. The critical dimension, defined by the vanishing of the Liouville kinetic term, is found to be D=26, the same as for the ordinary bosonic string theory. © 1988 The American Physical Society URL:
