A Fixed Point Theorem in Weak Topology for Successively Recurrent System of Set-Valued Mapping Equations and Its Applications

Kazuo HORIUCHI

Summary :

Let us introduce n ( ≥ 2) mappings f_i (i=1,,n ≡ 0) defined on reflexive real Banach spaces X_i-1 and let f_i:X_i-1 → Y_i be completely continuous on bounded convex closed subsets X_i-1⁽⁰⁾ ⊂ X_i-1. Moreover, let us introduce n set-valued mappings F_i : X_i-1 Y_i → F_c(X_i) (the family of all non-empty compact subsets of X_i), (i=1,,n ≡ 0). Here, we have a fixed point theorem in weak topology on the successively recurrent system of set-valued mapping equations:x_i ∈ F_i(x_i-1, f_i(x_i-1)), (i=1,,n ≡ 0). This theorem can be applied immediately to analysis of the availability of system of circular networks of channels undergone by uncertain fluctuations and to evaluation of the tolerability of behaviors of those systems.
