摘要

经典矩阵理论适用于复数;它对通常绝对值的依赖使它成为阿基米德理论。本文考虑了Gershgorin盘定理和对角占优矩阵的非阿基米德对偶。我们比较和对比阿基米德和非阿基米德的背景。一个显著的不同是，对角占优矩阵在非阿基米德设置中享有更多的结构。

Non-Archimedean Views on Gershgorin’s Theorem and Diagonal Dominance

Abstract Classical matrix theory works over the complex numbers; its reliance on the usual absolute value makes it an Archimedean theory. In this paper, we consider non-Archimedean counterparts of the Gershgorin disk theorem and diagonally dominant matrices. We compare and contrast the Archimedean and non-Archimedean contexts. A remarkable dissimilarity is that diagonally dominant matrices enjoy more structure in the non-Archimedean setting.

期刊介绍： The Monthly''s readers expect a high standard of exposition; they look for articles that inform, stimulate, challenge, enlighten, and even entertain. Monthly articles are meant to be read, enjoyed, and discussed, rather than just archived. Articles may be expositions of old or new results, historical or biographical essays, speculations or definitive treatments, broad developments, or explorations of a single application. Novelty and generality are far less important than clarity of exposition and broad appeal. Appropriate figures, diagrams, and photographs are encouraged. Notes are short, sharply focused, and possibly informal. They are often gems that provide a new proof of an old theorem, a novel presentation of a familiar theme, or a lively discussion of a single issue. Abstracts for articles or notes should entice the prospective reader into exploring the subject of the paper and should make it clear to the reader why this paper is interesting and important. The abstract should highlight the concepts of the paper rather than summarize the mechanics. The abstract is the first impression of the paper, not a technical summary of the paper. Excessive use of notation is discouraged as it can limit the interest of the broad readership of the MAA, and can limit search-ability of the article.
