Let G be an n  n lmost periodi (AP) matrix function de®ned on the real line R. By the AP factorization of G we understand its representation in the form q q Kq À , where q AE1 (q AE1 À ) is an AP matrix function with all Fourier exponents of its entries being non-negative (respectively, non-positiv
Let R be a complete blocked triangular matrix algebra over an infinite field F. Assume that R is not an upper triangular matrix algebra or a full matrix algebra. Ž . We prove that the minimum number s R such that R can be generated as an F-algebra by idempotents, is given by where m is the number
