Some new characterizations of m-asymmetric semiopen sets and M-asymmetric semicontinuous multifunctions will be investigated and several fundamental properties will be obtained. %K < %K i> %K m< %K /i> %K -Spaces %K < %K i> %K m< %K /i> %K -Semiasymmetric Open and Closed Sets %K Upper and Lower < %K i> %K M< %K /i> %K -Asymmetric Semicontinuous Multifunction %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=108282
