In this paper, we investigate the “angular changes” behavior of some subfamilies of Fourier coefficients of both integral and half-integral weight holomorphic cusp forms, thus one gets information about signs of the real an imaginary parts of these subfamilies. These give an extension of some recent results of Kohnen and his collaborators.

Abstract

These give an extension of some recent results of Kohnen and his collaborators.
