DESCRIPTION:We will discuss several selective properties of ideals on coun
 table sets. In the case of maximal ideals all those properties coincide an
 d are equivalent to the notion of selectiveness of a maximal ideal (a maxi
 mal ideal is selective iff its dual filter is a Ramsey ultrafilter)\, howe
 ver in general those selective properties differ from each other. We will 
 show some of their connections to ideal convergence of sequences of functi
 ons\, descriptive complexity of ideals and topological ways of representin
 g ideals. \n
