We study N=(0,2) deformed (2,2) two-dimensional models: geometric aspects, holomorphic properties and RG flow. We consider the N=(0,2) supercurrent supermultiplet and its anomalies, as well as an analog of the Konishi anomaly. This gives us a method for finding beta functions. Using instanton calculus we obtain exact expressions for beta functions in terms of anomalous dimensions analogous to the NSVZ beta function in four-dimensional Yang-Mills. \ \ Note: unusual day and time.
