The object of this paper is to generalize these results to higher level. Thus we want to study the space S£+1/2(4N) of cusp forms of weight fc + 1/2 on Γ0(4ΛΟ (Ν e N) which have a Fourier expansion s in (*). Because this will be our basic object of study, we n w break with tradition and redefine the level of a modular form of half-integral weight s N if the form satisfies a transformation law under Γ0(4Ν) and has a Fourier expansion s in (*); we also drop the "4" and the "+" and write Sk+i/2(N) instead * ^) i* °f T* (n). More generally, if χ is a DirichJet character
