Quasimodular forms: an introduction
Quasimodular forms generalize modular forms, and the derivatives of modular forms are quasimodular forms. This paper provides an introduction to some basic properties of quasimodular forms for the discrete group \(\mathrm{SL}(2, \mathbb Z)\) including the structure theorems for the spaces of quasimodular forms.
