General
The Diffform python package implements differential forms and poly-forms from differential geometry. It includes some usual operations found in exterior calculus, include exterior product, differential operator. The main advantage of this package over other differential form packages ( e.g. pycartan ) is that it allows for polyforms and there is no dependence on basis forms.
This package is a part-time project during my PhD, updates should be suspected to end eventually. Bugs and mistakes may (possibly will) be prevalent.
Documentation will be implemented when I find the time, when I have time I will try to implement comments in the class/functions as a rudimentary form of documentation.
ToDo List
This is the list of possible implementation, in an approximate order of priority (interest to me):
- Differential Forms
- Exterior Product
- Simplification of Forms
- Exterior Differential Operator
- Substitution of factors/forms
- Vector fields
- Generic tensor product
- Insertion of vector fields
- Generic Tensor Contractions
- Implement substitution for Tensors
- Hodge star given metric/frame (Working?)
- Spin connection computation
- [] Lie Derivative on generic Tensor (add weight)
- Fallback to symbolic Hodge star without basis (or if form isn't in basis)
- Solving 1-form simple linear equations
- Vector Field Commutator
- Separate G-Structure Commands into separate files/subfolders
Dependencies
Make sure you have the following python packages:
- wheel (needed for installing through pip)
- sympy
Installation
Package should be uploaded to pip fairly frequently and is currently under diffforms
