Hi all, This is just a short "me too" note. I am also interested in exterior algebras and differential forms in Sage, but am wondering how to incorporate these with Clifford algebras, Dirac operators, and the functional calculus of operators, especially in relation to the algebraic "user interface", the overall coercion scheme and the various existing implementations in Axiom, SymPy, etc.
I still have the GluCat ( http://glucat.sf.net ) C++ Clifford/exterior algebra library waiting to integrate into Sage. I have not yet published the Cython interface to GluCat, but that should not be difficult. One possible difficulty (besides the user interface design and coercion issues mentioned above) is that GluCat uses Boost in general and uBLAS linear algebra in particular. So as far as I can see, it would be easier to add GluCat to Sage via a Cython/spkg interface, rather than directly via C++ and C.
