摘要

本文旨在介绍和研究作用于巴拿赫网格之间的一类新的广义半弗雷德霍姆算子，称为阶半弗雷德霍姆算子。它强调了该类算子的一些有趣性质。此外，我们还获得了扰动性质。最后，我们讨论了使有序半弗雷德霍姆算子的邻接算子成为半弗雷德霍姆算子的条件。

Some new results about order Fredholm theory in Banach lattices

This paper aims to introduce and study a new generalized class of semi-Fredholm operators acting between Banach lattices called order semi-Fredholm operators. It highlights some interesting properties of this class. Also, a perturbation properties are obtained. Finally, we discuss the conditions that make the adjoint of an order semi-Fredholm operator be a semi-Fredholm operator.

期刊介绍： The purpose of Positivity is to provide an outlet for high quality original research in all areas of analysis and its applications to other disciplines having a clear and substantive link to the general theme of positivity. Specifically, articles that illustrate applications of positivity to other disciplines - including but not limited to - economics, engineering, life sciences, physics and statistical decision theory are welcome. The scope of Positivity is to publish original papers in all areas of mathematics and its applications that are influenced by positivity concepts.
