The capital `D` is notation for the partial derivative; `D[i]` means partial derivative with respect to the `i`th variable of the function (where indexing starts at 0). So `D[0](conjugate)(z)` means...

The following code, var('z') f = z*z.conjugate() f.derivative(z) produces z*D[0](conjugate)(z) + conjugate(z) Now I undestand where the problem might be, $z$ and $z^*$ are usually treated as...
