%0 Journal Article %T Saturated neighbourhood models of Monotonic Modal Logics %A Celani %A Sergio Arturo %J Revista de la Uni£¿3n Matem£¿£¿tica Argentina %D 2008 %I Uni¨®n Matem¨¢tica Argentina %X in this paper we shall introduce the notions of point-closed, point-compact, and m-saturated monotonic neighbourhood models. we will give some characterizations, and we will prove that the ultrafilter extension and the valuation extension of a model are m-saturated. %K monotonic modal logic %K neighbourhood frames and models %K m-saturated models %K ultrafilter extension %K valuation extension. %U http://www.scielo.org.ar/scielo.php?script=sci_abstract&pid=S0041-69322008000100010&lng=en&nrm=iso&tlng=en
