Remarks On @0-Injectivity

This article is a continuation of E. Momtahan’s work in which he studied the literature via countable injectivity. Along this line, @0-Ikeda-Nakayama rings have been studied and among other things, new characterizations of basically disconnected and extremally disconnected spaces have been given. Furthermore we will observe that a boolean ring is @0-self-injective if and only if it is an @0-IN ring.
