Abstract: | The paper studies Winer-Hopf factorization problem for matrix-functions of the second order defined on the unit circle of the complex plane. The element G 21 of these matrix-functions is assumed to be representable by combinations of the other three elements and two functions meromorphic in the interior and exterior of the circle. Some formulas for partial indices are obtained. |
