Description (last modified by )
If P
is a multivector field and f
is a scalar field then f.wedge(P)
is already defined
sage: M = Manifold(3, 'M') sage: X.<x,y,z> = M.chart() sage: ddX = X.frame() sage: ddx,ddy,ddz = ddX[:] sage: P = x*ddy.wedge(ddz) + y*ddz.wedge(ddx) + z*ddx.wedge(ddy) sage: f = M.scalar_field(x) sage: f.wedge(P).display() x*z d/dx/\d/dy - x*y d/dx/\d/dz + x^2 d/dy/\d/dz
but P.wedge(f)
is not:
sage: P.wedge(f) ... AttributeError: 'DiffScalarFieldAlgebra_with_category.element_class' object has no attribute '_ambient_domain'
This is the multivector field analogue of #28579.
