| Abstract: Composition operators on H^2 cannot---except trivially---be Toeplitz, or even ``Toeplitz plus compact.'' However there are natural ways in which they can be ``asymptotically Toeplitz.'' We show here that the study of such phenomena leads to surprising results and interesting open problems. |
