In this paper we first give a concept on mixed monotone semiflows and a condition forfunctional differential equations to generate a mixed monotone semiflows.

Using the theory of monotone semiflows,we study the asymptotic behavior of the solutions to a class of functional differential equations.

In this paper,using the method of mixed monotony,we construct mono-tone sequences that converge uniformly to the unique solution of periodic boundarv valueproblem for first order functional differential equations when the functions involved donot any monotone properties.

In this paper, using the metod of mixed monotony, we study the initial value problem for first order functional differential equations, some new results are obtained.

In this paper, we use the coupled fixed point theorem for mixed monotone condensing operators to obtain an existence, uniqueness and iterative approximation theorem of solutions of initial value problems for second order mixed monotone type of impulsive differential equations.

In this paper, We introduce the concept on mixed monotone semiflows and use mixed property of the semiflows, some ecological stability criterias for a delayed ecosystem are obtained.

This paper presents all sorts of nonsymmetric iterations and obtains existence and uniqueness theorms of solution to mixed monotone operator equation and provides their applications.

The results of experiments showed that hybrid halftoning aiming at the image tones can reproduce characters of the original image tone while reducing the impact of texture and making the tone conversion more natural.
