On the representation of a class of contractive matrix-valued functions

By a decomposition of L+ 2(Cn) in two orthogonal subspaces we obtain a representation of a matrix-valued function of the class JΠ, defined by Arov (Darlington realization of matrix-valued functions, Izv. Akad. Nauk. SSSR, Ser. Mat. Tom. 37 (1973), No. 6); (Math. USSR Izvestija 7 (1973), No. 6, 1295-...

Descripción
Sumario:By a decomposition of L+ 2(Cn) in two orthogonal subspaces we obtain a representation of a matrix-valued function of the class JΠ, defined by Arov (Darlington realization of matrix-valued functions, Izv. Akad. Nauk. SSSR, Ser. Mat. Tom. 37 (1973), No. 6); (Math. USSR Izvestija 7 (1973), No. 6, 1295-1326). Real matrix-valued functions of this class play an important role in methods of synthesis of scattering matrices of linear passive n-ports. © 1984.
