Error in the proof of below theorem!! http://www.mathematics21.org/binaries/addons.pdf My earlier attempt to describe normal reloids (where the normality is taken from “Each regular paratopological group is completely regular” article, not from the customary normality of the induced topological space) failed. After a…

read moreHaving a funcoid $latex f$ I defined what I call interior funcoid $latex f^\circ$. See this PDF file for a few equivalent definitions. Interior funcoid is a generalization of interior operator for a topological space. Interior funcoid is kinda dual funcoid. Note…
