For example,

with(Ore_algebra):
A:=diff_algebra([Dx,x],[Dy,y]):
`&*`:=rcurry(skew_product,A):
d:=Dx-I*Dy:
p:=2*y^2-3*y+1:
d&*(p&*d);

                                         2              2
  (-4 I y + 3 I) Dx + (3 - 4 y) Dy + (2 y  - 3 y + 1) Dx

                  2                             2              2
         + (-4 I y  + 6 I y - 2 I) Dx Dy + (-2 y  + 3 y - 1) Dy
