Demonstrates the background is supported by electromagnetic flux.
Provides a framework for further studies of string theory in curved spacetimes.
Abstract
An exact heterotic string theory on an AdS2xS2 background supported by an electromagnetic flux is found as a marginal deformation of an SL(2,R)xSU(2) WZW model.
