Abstract
Let be the functionally countable subalgebra of . Essential -spaces are introduced and investigated algebraically and topologically. It is shown that if is a proper essential -space, then is compact if and only if is a , where is the only non -point of and is the space of minimal prime ideals of which are not maximal. Quasi -spaces, -basically disconnect spaces, almost -spaces and almost essential -spaces are introduced and studied via essential -spaces. Finally, as a -ring where is an essential -space is investigated.
