My dear developers, right now, I'm working on my master thesis and my task is to implement characteristic classes (of the tangent bdl. of a manifold), such as the A-genus, into Sage. The implementation shall be based upon this <https://www.math.uni-potsdam.de/fileadmin/user_upload/Prof-Geometrie/Dokumente/Lehre/Lehrmaterialien/charakteristisch.pdf> piece of work by my supervisor. Briefly, one can compute the classes out of the curvature matrix and the corresponding power series.
So far, I've implemented the graded algebra of mixed differential forms and the next step will be the matrix framework for the desired classes. However, it might also be convenient to implement some methods into manifolds/differentiable/manifold.py directly. Is this idea worth a ticket? You wanna see the code I've done so far?
