%0 Journal Article %T On regular b-open sets in topological spaces %A A. Narmadha %A N. Nagaveni %A T. Noiri %J International Journal of Mathematical Analysis %D 2013 %I %X The purpose of this paper is to introduce and study regular bopensets (briefly rb-open sets) in topological spaces and obtain some oftheir properties. We introduce the rb-closure and discuss some basicproperties of the rb-closure. Also we study the new concepts of rb-closedspaces by means of filter bases. %K Topological spaces %K rb-open set %K rb-closed set %K rb-interior %K rbclosure %K rb-closed space %U http://www.m-hikari.com/ijma/ijma-2013/ijma-17-20-2013/narmadhaIJMA17-20-2013.pdf
