In this article, we continue studying of \( \mathcal {H}_Y \)-ideals. We introduce notions fixed \( \mathcal {H}_Y \)-ideals, free \( \mathcal {H}_Y \)-ideals and relative \( \mathcal {H}_Y \)-ideals as extensions of fixed z-ideal, free z-ideals and relative z-ideals, respectively. It has been shown that large amounts of the results of the papers in the literature about these topics are special cases of the results of this paper. We prove that Y is compact if and only if every proper \( \mathcal {H}_Y \)-ideal is a fixed \( \mathcal {H}_Y \)-ideal; if and only if every proper strong \( \mathcal {H}_Y \)-ideal is a fixed \( \mathcal {H}_Y \)-ideal. Also, we show that every proper ideal is a relative \( \mathcal {H}_Y \)-ideal, if and only if every proper ideal is a relative strong \( \mathcal {H}_Y \)-ideal, if and only if R is regular.

在$$ \ mathcal {H} _Y $$ HY上-理想

在本文中,我们继续研究\(\ mathcal {H} _Y \)- ideals。我们引入固定\(\ mathcal {H} _Y \)-理想,免费\(\ mathcal {H} _Y \)-理想和相对\(\ mathcal {H} _Y \)-理想作为固定z的扩展的概念-理想的自由z理想和相对z理想。已经表明,关于这些主题的文献中大量的论文结果是本文结果的特例。我们证明,当且仅当每个正确的\(\ mathcal {H} _Y \)- ideal是固定的\(\ mathcal {H} _Y \)时Y才是紧的-理想; 当且仅当每个适当的强\(\ mathcal {H} _Y \)- ideal是固定的\(\ mathcal {H} _Y \)- ideal。此外,我们表明,每一个正确的理想是一个相对\(\ mathcal {H} _Y \) -理想,当且仅当每一个正确的理想是一个相对强大的\(\ mathcal {H} _Y \) -理想,如果和仅当R为规则数时。
