摘要：Thomson's theorem implies that on the Bergman space over the unit disk if h is holomorphic on the closed unit disk, then there is a finite Blaschke product B such that h can be written as a function of B, and the commutant of the multiplication operator M_h by h equals that of M_B. In this talk we will see that it is essentially generalized to the Bergman space over an annulus under a mild condition. The situation is complicated compared with the classical Bergman space over the unit disk.We also consider the associated reducing subspaces of concerned multiplication operator.
