A Fixed Point Theorem in Weak Topology for Successively Recurrent System of Fuzzy-Set-Valued Nonlinear Mapping Equations and Its Application to Ring Nonlinear Network Systems

On uniformly convex real Banach spaces, a fixed point theorem in weak topology for successively recurrent system of fuzzy-set-valued nonlinear mapping equations and its application to ring nonlinear network systems are theoretically discussed in detail. An arbitrarily-level likelihood signal estimation is then established.
