Quasimodular forms and automorphic pseudodifferential operators of mixed weight
Automorphic pseudodifferential operators, Jacobi-like forms, Modular forms, Quasimodular forms
Jacobi-like forms for a discrete subgroup Γ of SL(2 , R) are formal power series which generalize Jacobi forms, and they are in one-to-one correspondence with automorphic pseudodifferential operators for Γ. The well-known Cohen–Kuznetsov lifting of a modular form f provides a Jacobi-like form and therefore an automorphic pseudodifferential operator associated to f. Given a pair (λ, μ) of integers, automorphic pseudodifferential operators can be extended to those of mixed weight. We show that each coefficient of an automorphic pseudodifferential operator of mixed weight is a quasimodular form and prove the existence of a lifting of Cohen–Kuznetsov type for each quasimodular form.
