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.
