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.

关键词: 向量均衡, 近似解, 广义凸性, 最优性条件, 对偶

Abstract:

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.

Key words: Vector Equilibrium, Approximate solution, Generalized convexity, Optimality conditions, Duality
