摘要:
We give a set of test functions for H-1(infinity), the algebra of bounded holomorphic functions on the disk with first derivative equal to 0; whose interpolation problem was studied by Davidson, Paulsen; Raghupathi and Singh (2009). We show that this set of test functions is minimal by relating these ideas to realization and interpolation problems.
