Superior subalgebras and ideals of BCK/BCI-algebras

Young Bae Jun, Seok Zun Song (2016)

Discussiones Mathematicae General Algebra and Applications

Similarity:

The notions of superior subalgebras and (commutative) superior ideals are introduced, and their relations and related properties are investigated. Conditions for a superior ideal to be commutative are provided.

On ideals consisting of topological zero divisors

Antoni Wawrzyńczyk (2000)

Studia Mathematica

Similarity:

The class ω(A) of ideals consisting of topological zero divisors of a commutative Banach algebra A is studied. We prove that the maximal ideals of the class ω(A) are of codimension one.

Ideals of BCI-algebras and their Properties

Chenglong Wu, Yuzhong Ding (2008)

Formalized Mathematics

Similarity:

In this article three classes of ideals are discussed: associative ideals, commutative ideals, implicative ideals and positive implicative ideals, and their elementary properties. Some of their properties and the relationships between them have not been proven yet, and will be completed in the following article.MML identifier: BCIIDEAL, version: 7.8.10 4.99.1005
