I started another ticket <https://trac.sagemath.org/ticket/27599>, just for my own (and maybe other's?) convenience. It's about the latex name of multiplied scalar fields.
Moreover, I've encountered a problem regarding the multiplication of my algebra. Suppose A and B are mixed differential forms, a is some differential form and f is a differentiable scalar field on M. Then, I get the following results: sage: A.__mul__(B) Mixed differential form A/\B on the 2-dimensional differentiable manifold M sage: f.__mul__(A) Mixed differential form f/\A on the 2-dimensional differentiable manifold M sage: A.__mul__(a) Mixed differential form A/\a on the 2-dimensional differentiable manifold M sage: a.__mul__(A) Mixed differential form A/\a on the 2-dimensional differentiable manifold M All fine, except the very last line. The coercions are working quite well so far - without any errors. Yet, what might explain the very different results? Can you give me a first hint, though not seeing the code?
