Naively, I would expect the following to work:
E.<x,y> = EuclideanSpace(2)
phi = E.diff_form(2)
phi[1, 2] = 1
show(integrate(integrate(phi, x, 0, 1), y, 0, 1))
but it fails with:
TypeError: unable to convert 2-form on the Euclidean plane E^2 to a symbolic expression
and I can't find anything about integration in the DiffFormFreeModule documentation. What is the right way to do this?ripple_carrySun, 02 May 2021 21:42:54 +0200https://ask.sagemath.org/question/56906/
