Abstract

The purpose of this paper is to investigate solutions U$_+$ and U$^+$ for the fuzzy relation equation R$\circ$U= T in cases of R < T, R $\leq$ T, and R = T, when R is irreflexive, U$_+$ ($\chi$$_i$, $\chi$$_k$)=$\bigwedge$[R($\chi$$_i$, $\chi$$_k$) << T($\chi$$_i$, $\chi$$_k$)], U$^+$ ($\chi$$_i$, $\chi$$_k$)=$\bigwedge$[R($\chi$$_i$, $\chi$$_k$)->T($\chi$$_i$, $\chi$$_k$)].
