### UNIFORMLY CONTINUOUS FUNCTIONS ON NON-HAUSDORFF GROUPOIDS

#### Mădălina Roxana Buneci

Abstract. The purpose of this paper is to study the notion of uniform continuity introduced in [1]. For a locally compact (not necessarily Hausdorff) groupoid endowed with pre-Haar systems (in the sense of [1] adapted to non-Hausdorff case) we prove that the space of bounded compactly supported functions which are left and right uniformly continuous on fibres can be made into a *-algebra and endowed with a (reduced) C*-norm. The advantage of working with uniformly continuous on fibres functions is the fact that even if the groupoid does not admit a continuous Haar system, various C*-algebras can be associated with it.
