Abstract

In this article, we continue the studying of HY\mathcal{H}_Y-ideals. We introducing two notions fixed and free HY\mathcal{H}_Y-ideals as an extension of fixed and free z-ideals in C(X) and relative HY\mathcal{H}_Y-ideals as an extension of relative z-ideals. It has been shown that a large amount of the results of the mentioned papers and generally 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 HY\mathcal{H}_Y-ideal is a fixed HY\mathcal{H}_Y-ideal; if and only if every proper strong H_Y-ideal is a fixed ideal. Also, we show that every proper ideal is a relative HY\mathcal{H}_Y-ideal, if and only if every proper ideal is a strong HY\mathcal{H}_Y-ideal; if and only if R is regular.
