Dear Isabelle-Users,

Does somewhere exist a theory development for
Affine n-dimensional transformations ?

Any kind of hint is appreciated.

What exactly do you need? I don't think we have the notion of "affine"
map as such, but we have linear maps of course, and an affine map is
just a combination of a linear map and a translation.

And we do have some results e.g. about how the Borel measure of a set
changes under an affine map.
