Asymptotic Moore-Penrose inversion of Toeplitz operators
The paper describes all sequences belonging to the algebra generated by the finite sequences of a block Toeplitz operator (PC) with piecewise continuous generating function defined on the unit circle. The problem is considered how to approximate the Moore-Penrose inverse of the Toeplitz PC operator supposed to be Fredholm.
