Conformally invariant field theory in two dimensions and strings in curved spacetime
- Brown Univ., Providence, RI (USA). Dept. of Physics
The formalism of conformally invariant field theory on a 2-dimensional real manifold with an intrinsic metric is developed in the functional integral framework. This formalism is used to study the relationships between reparametrization, Weyle, conformal and BRST invariances for strings in generic backgrounds. Conformal invariance of string amplitudes in the presence of back grounds is formulated in terms of the Virasoro condition. The consequences of these conditions are investigated in the case of specific backgrounds. Strings in group manifolds are discussed exactly. For a generic slowly varying spacetime metric and dilaton field, a perturbatively renormalized vertex operator solution of the Virasoro conditions is constructed.
