Contravariant representable functors take colimits to limits. Functors like these are called representable functors. This construction makes all sheaves into representable functors on certain categories of topological spaces. This functor is representable by a separated -scheme formula 34. Every Banach space is finitely representable in "c". A regular matroid is a matroid that is representable over all possible fields. An important goal in many settings is to determine whether a given functor is representable. It is conjectured that the representable numbers have positive natural density. The normalized range of representable numbers is from 16 to 16 (approx. Both alternatives provide exactly the same range of representable values. This replacement also happens before a syllabic , as in "button" (representable as ). The symbol was representable in HTML as or . Sarajevo has one of the most representable commercial infrastructures in South-East Europe.
