Keywords:
fuzzy $G_\delta$-neighbourhood; fuzzy $G_\delta$–$T_1$-ordered spaces; fuzzy $G_\delta$–$T_2$ ordered spaces
Summary:
$G_\delta$-separation axioms are introduced in ordered fuzzy topological spaces and some of their basic properties are investigated besides establishing an analogue of Urysohn’s lemma.
