相补理论的研究,首先开始于60年代早期Lemke、Cottle和Dantzig对以及其他作者的一些工作.随后,相补理论大量地应用于数学和工程技术的许多领域,最近,为了研究大量产生于介质渗流、弹性接触、控制与优化、经济与运输平衡以及弹性薄板的临界平衡状态等方面的线性和非线性问题,人们从不同的角度出发把相补理论加以改进和推广(参见[4-11],[13-29]及其参考文献). 相似文献

本文研究了无限维空间里集值映射的多目标规划问题。主要结果是:当目标函数为类凸的集值映射时,其目标空间里的有效点集是连通的;若目标函数为C-凸的集值映射时,其有效解集也连通。 相似文献

Calmness of multifunctions is a well-studied concept of generalized continuity in which single-valued selections from the image sets of the multifunction exhibit a restricted type of local Lipschitz continuity where the base point is fixed as one point of comparison. Generalized continuity properties of multifunctions like calmness can be applied to convergence analysis when the multifunction appropriately represents the iterates generated by some algorithm. Since it involves an essentially linear relationship between input and output, calmness gives essentially linear convergence results when it is applied directly to convergence analysis. We introduce a new continuity concept called ‘supercalmness’ where arbitrarily small calmness constants can be obtained near the base point, which leads to essentially superlinear convergence results. We also explore partial supercalmness and use a well-known generalized derivative to characterize both when a multifunction is supercalm and when it is partially supercalm. To illustrate the value of such characterizations, we explore in detail a new example of a general primal sequential quadratic programming method for nonlinear programming and obtain verifiable conditions to ensure convergence at a superlinear rate. 相似文献

We present a local convergence analysis for higher order methods in order
to approximate a locally unique solution of an equation in a Banach space setting. In
earlier studies, Taylor expansions and hypotheses on higher order Fréchet-derivatives
are used. We expand the applicability of these methods using only hypotheses on the
first Fréchet derivative. Moreover, we obtain a radius of convergence and computable
error bounds using Lipschitz constants not given before. Numerical examples are also
presented in this study. 相似文献

We consider the convergence of composition operators on Hardy-Smirnov space over a simply connected domain properly contained in the complex plane. The convergence of the power of a composition operator is also considered. Our approach is a method from Joel H. Shapiro and Wayne Smith's celebrated work (Journal of Functional Analysis 205 (2003) 62-89). The resulting space is usually not the one obtained from the classical Hardy space of the unit disc by conformal mapping. 相似文献
