Duke, W. Hyperbolic distribution problems and half-integral weight Maass forms. (English) Zbl 0628.10029 Invent. Math. 92, No. 1, 73-90 (1988). A recent estimate of H. Iwaniec [Invent. Math. 87, 385-401 (1987)] for certain Fourier coefficients of a holomorphic cusp form of weight half an odd integer is extended to include a class of Maass forms. Several applications are given, in particular the uniform distribution of Heegner points and cycles on the hyperbolic surface PSL(2,\({\mathbb{Z}})\setminus H\).
