Abstract

Let GG be a minimal locally compact groupoid with compact metrizable unit space and let EE be a continuous GG-Hilbert bundle. We show that a bounded continuous cocycle c:G\rarEc: G\ra r^*E is necessarily a continuous coboundary. This is a groupoid version of a classical theorem of Gottschalk and Hedlund.
