This yields Siegel modular forms and Hermitian modular forms. In later work\, Kudla conjectured that the analogous generating series of cycles in the Chow group is modular\, too. The orthogonal case of the conjecture was established more than 10 years ago. We resolve the conjecture in the unitary case. In this talk\, we explain in particular the role of automatic convergence results in the theory: how they arise and what techniques we currently have to prove them. \nZoom (680 4828 0736\, The password is the first Fourier coefficient of the modular j-function (as digits)).

For this we introduce orthogonal lowering and raising operators. Basic results are the description of the spaces of quasimodular forms in terms of vectorvalued modular forms and the interaction with the theta lift. In particular\, we give a criterion when the theta lift of a quasimodular form is again quasimodular (it is not always the case). In the second part of the talk I will explain how these quasimodular forms appear in the Gromov-Witten theory of Enriques surfaces. They also want to appear in the Gromov-Witten theory of K3 surfaces\, but actually more general automorphic objects there. Based on joint work with Brandon Williams. \nZoom (680 4828 0736\, The password is the first Fourier coefficient of the modular j-function (as digits)).

Its congruence with stable forms on GSp(4) can be used to produce a lower bound on the Selmer group of the Rankin-Selberg product of the two modular forms. We study this congruence by using Rallis inner product formula\, Bessel periods and Furusawa’s pullback formula\, together with p-adic interpolation. \nZoom (680 4828 0736\, The password is the first Fourier coefficient of the modular j-function (as digits)).
