comment Identifying a special function from its power series
Thanks, that is a more parameter version of the Hypergeometric than I am used to! It comes from looking at the eigenvalues of the Hodge Laplacian in the 1-forms of the noncommutative sphere (guess q=1 is just commutative sphere). The sum, evaluated at x=-1, is used in finding the normalisation of the eigen-1-forms in the Hodge inner product. I am hoping that knowing the classical analogue will help in the quantum case.

comment when is an algebra map conjugate to a star algebra map
Thanks! That seems to be a good answer, and gives me other things to look at.

comment Divisors, factorisations of matrix valued functions, and the Lorentz group
This would give a family of varieties, graded by the number of blow-ups, and on which the group acting would act by shifting the blown-up points. The problem would be to construct some non-trivial factorisation on (matrix valued) sections of bundles which would have residues on the blown-up points. This may be possible, but I was really hoping for other answers which would involve the geometry of the construction to give a single manifold on which the group acted - this may be too much. thanks for the comment.

comment rank of fin gen projective modules over C* algebras
If I accept an answer, does it take the original question out of consideration? I would rather not do that, as I would really like to find out about the multiplicativity (paragraph added in question about another way to look at that). So much e=protocol to learn... Anyway, I am now happier - thanks.
