Abstract
In this paper we continue to study various types of closures in -spaces. The main results are related to the construction and illustration of examples that allow us to understand the relationship between -closed, --closed, weakly -closed and weakly --closed spaces for each . The relation of these classes in Lindel\"{o}f spaces is shown. Some of the solved problems formulated by D. Dikranjan and E. Giuli are presented in the examples.
