For a locally compact groupoid with a fixed Haar system and quasi-invariant measure ,we introduce the notion of -measurability and construct the space 1 (, , ) of absolutely integrablefunctions on and show that it is a Banach -algebra and a two-sided ideal in the algebra ()of complex Radon measures on . We find correspondences between representations of on Hilbertbundles and certain class of nondegenerate representations of 1 (, , ).
