摘要: We constructively solve a pair of band-limited generalizations the Adamjan—Arov—Krein problem. The first one consists in extending function given on proper subset unit circle to whole so as make it close possible meromorphic with prescribed number poles, sup norm, while meeting some gauge constraint. second directly approximating by restriction function, again
