关于映射的半正则性

On semiregularity of mappings

R. Cibulka, M. Fabian, A. Y. Kruger

摘要:

有两种基本方法可以通过固定定义中涉及的一个点来削弱著名的度量正则性的定义。第一个由此产生的性质被称为度量次正则性,并在过去的几十年中吸引了很多关注。另一方面,后一个性质,我们称之为半正则性,可以在几个名称和相应的结果分散在文献中。我们提供了一个独立的材料收集和扩展现有的理论上的主题。我们证明了一个明确的关系与其他的规律性,例如,与所谓的开放性与线性率在参考点的等价性。在特殊情况下,我们得到了必要和/或充分条件的原始和对偶类型。作为应用,我们研究了单值部分不一定可微的广义方程的一个不精确Newton型格式。

英文摘要:

There are two basic ways of weakening the definition of the well-known metric regularity property by fixing one of the points involved in the definition. The first resulting property is called metric subregularity and has attracted a lot of attention during the last decades. On the other hand, the latter property which we call semiregularity can be found under several names and the corresponding results are scattered in the literature. We provide a self-contained material gathering and extending the existing theory on the topic. We demonstrate a clear relationship with other regularity properties, for example, the equivalence with the so-called openness with a linear rate at the reference point is shown. In particular cases, we derive necessary and/or sufficient conditions of both primal and dual type. As an application we study an inexact Newton-type scheme for generalized equations with not necessarily differentiable single-valued part.
