理想空间:环的结构空间的一种推广

Ideal spaces: An extension of structure spaces of rings

Themba Dube, Amartya Goswami

AI总结:

本文提出理想空间概念以建立环的任意理想类的结构空间型理论,刻画了清醒理想空间,引入强不连通空间概念并证明相关结论,还给出谱连通的充分条件。

摘要:

对于环的任意理想类,是否存在结构空间类型的理论?本文提出的理想空间(ideal spaces)使得这类研究成为可能,我们的理论涵盖但不限于素理想、极大理想、极小素理想、强不可约理想、不可约理想、完全不可约理想、真理想、极小理想、准素理想、诣零理想、幂零理想、正则理想、根理想、主理想、有限生成理想。我们刻画了清醒(sober)的理想空间。我们引入了强不连通空间的概念,并证明对于Jacobson根为零的环,包含环的所有极大理想的强不连通理想空间意味着环中存在非平凡幂等元。我们还给出了谱连通的一个充分条件。

英文摘要:

Can there be a structure space-type theory for an arbitrary class of ideals of a ring? The ideal spaces introduced in this paper allows such a study and our theory includes (but not restricted to) prime, maximal, minimal prime, strongly irreducible, irreducible, completely irreducible, proper, minimal, primary, nil, nilpotent, regular, radical, principal, finitely generated ideals. We characterise ideal spaces that are sober. We introduce the notion of a strongly disconnected spaces and show that for a ring with zero Jacobson radical, strongly disconnected ideal spaces containing all maximal ideals of the ring imply existence of non-trivial idempotent elements in the ring. We also give a sufficient condition for a spectrum to be connected.
