Jacobi-like forms, Modular forms, Quasimodular forms, Rankin–Cohen brackets, Theta series
A quasimodular form ϕ of depth at most m corresponds to holomorphic functions (Formula presented.). Given nonnegative integers (Formula presented.) and (Formula presented.) with (Formula presented.), we introduce a linear differential operator (Formula presented.) of order (Formula presented.) on modular forms whose coefficients are given in terms of derivatives of the functions (Formula presented.). We then show that Rankin–Cohen brackets of modular forms can be expressed in terms of such operators. As an application, we obtain differential operators associated to certain theta series studied by Dong and Mason.
