 Fuzzy $r$-minimal $\alpha$-open sets on fuzzy minimal spaces Commun. Korean Math. Soc. 2012 Vol. 27, No. 3, 603-611 https://doi.org/10.4134/CKMS.2012.27.3.603Printed September 1, 2012 Won Keun Min Kangwon National University Abstract : We introduce the concept of fuzzy $r$-minimal $\alpha$-open set on a fuzzy minimal space and some basic properties. We also introduce the concepts of fuzzy $r$-$M$ $\alpha$-continuous and fuzzy $r$-$M$($M^*$) $\alpha$-open mappings, and investigate characterization for such mappings. Keywords : $r$-minimal semiopen, $r$-minimal $\alpha$-open, fuzzy $r$-$M$ continuous, fuzzy $r$-$M$ $\alpha$-continuous, fuzzy $r$-$M$ semicontinuous, $r$-$M$($M^*$) $\alpha$-open mappings MSC numbers : 54C08 Downloads: Full-text PDF
