A derivation on Jacobi forms: Oberdieck derivation (original) (raw)
The aim of this very short note is to give details on Oberdieck derivation. This is an unpublished companion to the work Formal deformations of the algebra of Jacobi forms and Rankin-Cohen brackets by the same authors. We build a natural derivation on Jacobi forms that extends Serre derivation. Our construction has been influenced by a construction of some differential operator by Oberdieck in [Obe14] and hence we shall call this derivation the Oberdieck derivation (see also [DLM00, GK09, MTZ08]). References for the Weierstraß ℘ and ζ functions are [Lan87, Ch. 18], [Sil94, Ch. 1] and [CS17, Ch. 2].

Rankin-Cohen deformations of the algebra of Jacobi forms
arXiv: Number Theory, 2017
The aim of this work is to emphasize the arithmetical and algebraic aspects of the Rankin-Cohen brackets in order to extend them to several natural number-theoretical situations. We build an analytically consistent derivation on the algebra J of weak Jacobi forms. From this derivation, we obtain a sequence of bilinear forms on J that is a formal deformation and whose restriction to the algebra M of modular forms is an analogue of Rankin-Cohen brackets associated to the Serre derivative. Using a classification of all admissible Poisson brackets, we generalize this construction to build a family of Rankin-Cohen deformations of J. The algebra J is a polynomial algebra in four generators. We consider some localization K of J with respect to one of the generators. We construct Rankin-Cohen deformations on K. We study their restriction to J and to some subalgebra of K naturally isomorphic to the algebra of quasimodular forms.
Formal deformations of the algebra of Jacobi forms and Rankin–Cohen brackets
Comptes Rendus. Mathématique, 2021
This work is devoted to the algebraic and arithmetic properties of Rankin-Cohen brackets allowing to define and study them in several natural situations of number theory. It focuses on the property of these brackets to be formal deformations of the algebras on which they are defined, with related questions on restriction-extension methods. The general algebraic results developed here are applied to the study of formal deformations of the algebra of weak Jacobi forms and their relation with the Rankin-Cohen brackets on modular and quasimodular forms. Résumé. Ce travail est consacré aux propriétés algébriques et arithmétiques des crochets de Rankin-Cohen permettant de les définir et de les étudier dans plusieurs situations naturelles de la théorie des nombres. Il se concentre sur la propriété qu'ont ces crochets d'être des déformations formelles des algèbres sur lesquelles ils sont définis, avec des questions connexes sur les méthodes de restriction-extension. Les résultats algébriques généraux développés ici sont appliqués à l'étude des déformations formelles de l'algèbre des formes de Jacobi faibles et leur relation avec les crochets de Rankin-Cohen pour les formes modulaires et quasimodulaires.
Differential Operators on Jacobi Forms of Several Variables
Journal of Number Theory, 2000
In this paper we study the Rankin-Cohen type bilinear differential operators, more generally, multilinear differential operators on the space of Jacobi forms on H × C n as well as on the space of modular forms on the orthogonal group O(2, n + 2). These types of Jacobi forms have been studied by Gritsenko and Krieg.
