The existence, uniqueness and non-symmetric iterative approximation of solutions for a class of systems of mixed monotone operator equations are discussed. As an application, we utilize, the results presented in this paper to study the existence and uniqueness problems of common solutions for a class of systems of functional equations arising in dynamic programming of multistage decision processes and a class of systems of nonlinear integral equation. The results obtained in this paper not only answer an open question suggested in [3] but also generalize the corresponding results of [1],[2]. 展开更多

It exists extensively in the research of nonlinear differential and integral equations. Generally, the research of mixed monotone operators in partially ordered Banach spaces requires compactness, continuity or concavity-convexity of the operators. In this paper, without any compact and continuous assumption, we obtain some new existence and uniqueness theorems of positive fixed point of e-concave-convex mixed monotone operators in Banach spaces partially ordered by a cone, which extends the existing corresponding results. 展开更多

By using the theory of the cone and partial ordering. It is studied that theexistence 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 Aand B can be decomposed A = A1+A2,B = B1+B2, A1 and B1 are mixed monotone, A2and B2 are anti-mixed monotone. The results preeented here improve and generalize somecorresponding results of mixed monotone operator equations. 展开更多

Here, the restrictions on {η k} are very different from the ones on {η k}, given by He et al (Science in China Ser.

The purpose of this paper is to study the solution of 0∈ T(x) for an H- monotone operator introduced in [Fang and Huang, Appl. Math. Comput. 145(2003)795- 803] in Hilbert spaces, which is the first proposal of it's kind. Some strong and weak convergence results are presented and the relations between maximal monotone operators and H-monotone operators are analyzed. Simultaneously, we apply these results to the minimization problem for T = δf and provide some numerical examples to support the theoretical findings. 展开更多

A new system of the set-valued mixed quasi-variational-like inclusions (SSMQVLI) involving H-η-monotone operators is studied in general Banach spaces without uniform smoothness. By using the resolvent operator technique of H-η-monotone operators, a new iterative algorithm for finding approximate solutions to SSMQVLI is proposed. It is shown that the iterative sequences generated by the algorithm converge strongly to the exact solution of SSMQVLI under appropriate assumptions. These obtained new results have extended and improved previous results. 展开更多

In this article, we consider the improved gradient method by the hybrid method in mathematical programming [i0] for solving the variational inequality problem for {AN} and prove strong convergence theorems.
