Recently J. Agler studied the class S d of scalar-valued, analytic functions of d complex variables f for which f (T 1 , ..., T d ) has norm at most 1 for any collection of d commuting contractions (T 1 , ..., T d ) on a Hilbert space H. Among other results he obtained a characterization of such fun
