Szukana fraza: [Abstract = "It is shown that a certain Bezout operator provides a bijective correspondence between the solutions of the matrix quadratic equation and factorizatons of a certain matrix polynomial G\(\[lambda\]\) \(which is a specification of a Popov\-type function\) into a product of row and column reduced polynomials. Special attention is paid to the symmetric case, i.e. to the Algebraic Riccati Equation."]
