  • Ticket #17909 – Description

    v20 v42  
    11This 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.

    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?
     10The ticket also adds support for listing the homogeneous and quasi parts of an element and fixes some bugs.
