Reducing Supersymmetry of Two-dimensional Sigma Models Down to N=(0,2)
Arkady Vainshtein, Univ. of Minn. & KITP

We study of N=(0,2) deformed (2,2) two-dimensional models, in particular,geometric aspects and holomorphic properties of these models. We derive a numberof exact relations for the β functions in terms of the anomalous dimensions analogous to the NSVZ beta function in four-dimensional Yang-Mills. We also consider the N=(0,2) supercurrent supermultiplet and its anomalies, as well as the ``Konishi anomaly." This gives us another method for finding two-loop beta functions.
