Ticket #17909 – Description
v20 v42 1 1 This ticket adds support for Rankin Cohen brackets for (quasi) modular forms. 2 The formulas shouldn't change for Hecke triangle groups.3 4 The ticket also adds support for listing the homogeneous and quasi parts of an element and fixes some bugs.5 2 6 3 See: 7 8 4  http://arxiv.org/abs/math/0509653 9 5  http://arxiv.org/abs/1306.3634v2 … … 12 8 http://math.univbpclermont.fr/~royer/ens/Mali/M2_Mali.html 13 9 14 Possible Todos: 15  Review the definition for more general analytic types (quasi weak/meromorphic forms) 16  Restrict/validate the parameters s, t 17  Review the algebraic structure of the bracket: 18 If s or t is None the bracket is no longer bilinear but it satisfy a Leibnitz rule? 19  Explore alternative brackets 20  Extend the definition from form spaces to form rings? 10 The ticket also adds support for listing the homogeneous and quasi parts of an element and fixes some bugs.
