ec-Filters and ec-ideals in the functionally countable subalgebra of C*(X)

Veisi, Amir (Universitat Politècnica de València, 2019-10-01)

[EN] The purpose of this article is to study and investigate ec-filters on X and ec-ideals in C*c (X) in which they are in fact the counterparts of zc-filters on X and zc-ideals in Cc(X) respectively. We show that the ...
On the locally functionally countable subalgebra of C(X) on locally functionally countable subalgebra of C(X)

Karamzadeh, O. A. S.; Namdari, M.; Soltanpour, S. (Universitat Politècnica de València, 2015-10-01)

[EN] Let $C_c(X)=\{f\in C(X) : |f(X)|\leq \aleph_0\}$, $C^F(X)=\{f\in C(X): |f(X)|<\infty\}$, and $L_c(X)=\{f\in C(X) : \overline{C_f}=X\}$, where $C_f$ is the union of all open subsets $U\subseteq X$ such that ...
