Abstract: In this paper we deal with the relation $$ \lim _\alpha \lim _\alpha X=\lim _\alpha X$$ for a subset $X$ of $G$, where $G$ is an $\ell$-group and $\alpha$ is a sequential convergence on $G$.

Keywords: convergence $\ell$-group, disjoint subset, direct product, lexico extension

Classification (MSC2000): 06F15, 22C05
