We find that the compactified string is described by a conformal invariant system for both the four dimensional and for the compact six dimensional variables. The four dimensional sector is found to be invariant under a non-critical N ≤ 2 superconformal transformations.enSpinorTwistorsSuperstringConformal Field Models in String TheorySuperstrings and Heterotic StringsArtículoDOI: 10.1088/1126-6708/2005/10/105
