WebShift operators on Hilbert spaces of analytic functions play an important role in the study of bounded linear operators on Hilbert spaces since they often serve as models for various classes of linear operators. For example, "parts" of direct sums of the backward shift operator on the classical Hardy space H2 model certain types of contraction operators … WebMar 31, 2005 · Published 31 March 2005. Mathematics. We study the backward shift operator on Hilbert spaces H α (for α > 0) which are norm equivalent to the Dirichlet-type spaces D α . Although these operators are unitarily equivalent to the adjoints of the forward shift operator on certain weighted Bergman spaces, our approach is direct and … hsbc bermuda telephone banking
