ELIMINATING AMBIGUITIES FOR QUANTUM CORRECTIONS TO STRINGS MOVING IN AdS4×ℂℙ3

Abstract

We apply a physical principle, previously used to eliminate ambiguities in quantum corrections to the two-dimensional kink, to the case of spinning strings moving in AdS 4×ℂℙ3, thought of as another kind of two-dimensional soliton. We find that this eliminates the ambiguities and selects the result compatible with AdS/CFT, providing a solid foundation for one of the previous calculations, which found agreement. The method can be applied to other classical string "solitons."
