Remarks on H/sup infinity / optimization multivariate distributed systems

The results of a study of H/sup infinity /-optimization for multivariable distributed systems are summarized. A skew Toeplitz framework has been used. The problem has been reduced to finding the singular values of a certain operator (the so-called four-block operator). Depending on the specific problem considered, the corresponding four-block operator can be simplified to a two-block or one-block operator. This is specialized to the multivariate two-block case. A procedure for the computation of the eigenvalues of this operator is described.
