Abstract

A multiset is a collection of objects in which repetition of elements is essential. This
paper is an attempt to generalize the notion of filters in the multiset context. In
addition, many deviations between multiset filters and ordinary filters have been
presented. The relation between multiset filter and multiset ideal has been mentioned.
Many properties of multiset filters, multiset ultrafilters, and convergence of multiset
filters have been introduced. Also, the notions of basis and subbasis have been
mentioned in the multiset context. Finally, several examples have been studied.
