Abstract
The purpose of this paper is to study indefinite functions of orderk on commutative locally compact groups. In section 3 we establish some fundamental properties of these functions. Using the results of this section we get a characterization for indefinite functions of order one (section 4). In section 5 we give a decomposition of measurable indefinite functions.
