摘要
该文研究一类约束向量均衡问题(CVEP)近似拟弱有效解的最优性条件和对偶定理.首先,建立了问题(CVEP)近似拟弱有效解关于近似次微分形式的最优性必要条件.其次,引入了一种广义凸性的概念,称之为近似伪拟type-I函数,并在其假设下,获得了问题(CVEP)近似拟弱有效解的最优性充分条件.最后,引入了问题(CVEP)的广义近似Mond-Weir对偶模型,并建立其与原问题间关于近似拟弱有效解的对偶定理.
In this paper,we study the optimality conditions and duality theorems for a class of Constrained Vector Equilibrium Problem(CVEP)with respect to approximate quasi weak efficient solutions.Firstly,a necessary optimality condition related to approximate subdifferential of approximation quasi weak efficient solution to problem(CVEP)is established.Secondly,a kind of generalized convexity,named pseudo quasi type-I function,is introduced,and under its assumption,a sufficient optimality condition is also obtained.Finally,the generalized approximate Mond-Weir dual model of problem(CVEP)is presented,and the dual theorems between with the primal problem are established.
