# finitary closure operator in a sentence

- A
*finitary closure operator* with this property is called a matroid. *Finitary closure operators* with this property give rise to antimatroids.- The convex hull in " n "-dimensional Euclidean space is another example of a
*finitary closure operator*. - The operator \ langle \ rangle is a
*finitary closure operator* on the set of subsets of | \ mathcal A |. - The function that maps every subset of a given field to its algebraic closure is also a
*finitary closure operator*, and in general it is different from the operator mentioned before. - It's difficult to find
*finitary closure operator* in a sentence. *Finitary closure operators* that generalize these two operators are studied in model theory as dcl ( for " definable closure " ) and acl ( for " algebraic closure " ).
