By J. W. Helton and M. R. James

This paper gives formulas for J-phase outer factorization of nonlinear systems and listing properties which are proved about them. Earlier work with Ball did J- inner outer factorization of stable systems, but the unstable case requires a vastly different construction. Also in the same announcement we give some tuning of the James-Baras solution of the nonlinear H control problem. One must add a hypothesis to insure internal stability of the closed loop control system.
