Abstract

Abstract: By using the theory of the cone and partial ordering. It is studied that the existence and uniqueness of solutions for a non-monotone binary operator equation A(x, x)= x and operator system of equations A(x,x)=x,B(x,x)=x in Banach spaces. Where A and B can be decomposed A=A₁+A₂, B=B₁+B₂, A₁ and B₁ are mixed monotone, A₂ and B₂ are anti-mixed monotone. The results presented here improve and generalize some corresponding results of mixed monotone operator equations.

Key words: cone , and , partial ordering, operator equations, anti-mixed monotone
