摘要:

广义混合拟变分不等式(GMQVI) 是变分不等式的推广。变分不等式及其推广模型被广泛地应用在经济学、交通、最优控制等领域。基于广义投影算子的相关性质和GMQVI解的特征, 在一定的单调性和紧性假设下, 本文在自反Banach空间中给出了问题(GMQVI) 的正则化间隙函数, 并由此构造了D-间隙函数。同时利用这些间隙函数, 得到了基于正则化间隙函数的局部误差界, 和利用D-间隙函数及正则项刻画的全局误差界。

关键词: 广义混合拟变分不等式, 间隙函数, 误差界

Abstract:

A generalized mixed quasi-variational inequality (GMQVI) is a generalization of the variational inequality. Variational inequalities and their generalization are widely used, for instance, economics, transportation and optimal control. Based on the intrinsic properties of the generalized projection operator, under certain assumptions of monotonicity and compactness, this paper gives the regularized gap function for generalized mixed quasi-variational inequality problems in reflexive Banach spaces, which in turn induces the D-gap function for GMQVI by the difference of two regularized gap functions. And using these gap functions, the local error bound described by the regularized gap function and the global error bound characterized by the D-gap function and the regularization term are obtained.

Key words: generalized mixed quasi-variational inequalities, gap functions, error bounds
