چکیده
|
let $l_c(x)={fin c(x) : overline{c_f}=x}$, where $c_f$ is the union of all open subsets $usubseteq x$ such that $|f(u)|leqaleph_0$. the concepts of $e_l-$filters and $e_l-$ideals has been introduced and studied in $l^*_c(x)$. it is shown the maximal ideals of $l^*_c(x)$ are in one-to-one correspondence with the $e_l$-ulterafilters on $x$ and also , the sets of $e_l$-ulterafilters and $z_l$- ultrafilters are in one-to-one correspondence. it is also shown that the sets of maximal ideals of $c_l(x)$ and $c^*_l(x)$ have the same cardinality.
