Brown, Francis; Hain, Richard Algebraic de Rham theory for weakly holomorphic modular forms of level one. (English) Zbl 1422.11083 Algebra Number Theory 12, No. 3, 723-750 (2018). Summary: We establish an Eichler-Shimura isomorphism for weakly modular forms of level one. We do this by relating weakly modular forms with rational Fourier coefficients to the algebraic de Rham cohomology of the modular curve with twisted coefficients. This leads to formulae for the periods and quasiperiods of modular forms.
