Holomorphic projection for sesquiharmonic Maass forms
摘要
We study the holomorphic projection of mixed mock modular forms involving sesquiharmonic Maass forms. As a special case, we numerically express the holomorphic projection of a function involving real quadratic class numbers multiplied by a certain theta function in terms of eta quotients. We also analyze certain shifted convolution L-series involving mock modular forms and bound certain shifted convolution sums.
