摘要 In this papert we study the existence of solutions and boundary solutions tothe following system of operator equations in partial ordering sets.... We do not assume any topological structure or alg...
摘要 In this papers the Fritz John conditions and Kuhn-Tucker conditions for majoroptimal solutions and major efficient solutions of multiobjective programming are givenand proved.
摘要 In this paper, we use the contraction principle and the Leray-Schauder principle to deal with the existence of periodic solutions of the Volterra integral differential equation. Some new existence ...
In this paper, we study the existence and global asymptotic stability of positive periodic solutions of a delayed periodic predator-prey system with Holling II type functional response. By use of the ...
A method for obtaining the explicit pointwise bounds on solutions to the general form of linear systems of Volterra integral inequalities in n independent variables is recomended. All known results re...
Concepts revolving around "displaced cones" are used to extend the ideas of nondominated solutions in multiobjective programming. Necessary and sufficient conditions are formed around the additive mod...
In this article we discuss the existence of solutions for a class of controlled systems governed by nonlinear differential inclusion where principal operator A is a nonlinear monotone operator. Using...
In this paper we establish the space-time integrality for solutions of some higherorder evolution equations in Besov space, by devoted to the technology of determined indexand functional analysis.
Even for elliptic variational inequality systems with degenerate ellipticity in the form of (1) the boundedness and regularity are unsolved for general obstacle problems. In this paper the C~(1,α) reg...
In this papert a cutting planelnethod is presented for solving the linear BLPP. An optimality criterion for the linear BLPP is derived from two related linear programs constructed by using the complem...
Major efficiency is an efficiency theory of multiobjective programming, whichis based on the law of majority. For the case that the feasible region is a finite set, paper [3] gave a comparison-number ...
This paper deals with the existence and nonexistence of global positive solutions of initial and boundary value problem for the general activator-inhibitor model... In this paper, we do not restrict ...
Consider the general competitive system \dot{u}=uM_1(t;u,v), \dot{v}=vM_2(t;u,v), where \partial M_1/\partial v <0, \partial M_2/\partial u <0, M_i(t+T; u,v) = M_i(t; u, v), i =1, 2. under soniccondit...
In this paper, we introduce the comparison number for one feasible solutioncompared with another. With the help of it the comparison-number method for finding the major optimal solutions aud major eff...
Using the monotone operator theory, we prove a convergent relation betweensolutions of a kind of nonlinear singular perturbation problem and their limit problem, andgive a boundary integral identity w...
