Resumen de On weak harmonic maass-modular grids of even integral weights

Pavel Guerzhoy

• A number of examples of families of weak Maass forms and modular forms which satisfy a striking equality between their $q$-expansion coefficients appeared recently. One can formulate this equality by saying that these coefficients constitute a grid. In this paper we consider the simplest setting of even integral weight and full modular group. We prove that for every positive even integral weight a grid exists and is unique.
