Andrew D. Lewis's Mathematica programs
- Affine: Some affine
differential geometry functions.
- Constraints: There are
some functions here to do things for constrained mechanical systems in the
affine connection framework.
- Coordinates: There
are a (very) few functions for doing coordinate changes for tensors.
- InnerProduct: Some
basic operations for inner products spaces.
Simple mechanical systems with symmetry.
