Sethi, P. L.; Poonam, Km. Inversion formulas for infinite generalized Toeplitz matrices of variable order. (Hindi. English summary) Zbl 1193.15003 Vijnana Parishad Anusandhan Patrika 44, No. 3, 219-232 (2001). Summary: Inversion formulas are obtained for a certain class of infinite matrices of variable order that possess displacement structure similar to that of finite block Toeplitz matrices of variable order. Consequences are symmetric inversion formulas for infinite Toeplitz plus Hankel matrices of variable order.
