Toeplitz Operators Associated with Isometries
Shift analysis includes abstract treatments of inner-outer factorization problems, the factorization problem for nonnegative functions on a circle, and Szegó's infimum problem (for scalar or operator valued functions).These problems are here generalized to a setting where the shift operator is replaced by a pair of isometries.<x> 00 K= Z®Vke, e …
