Not directly. For now you would have to treat a complex number as a
vector. There is a Blueprint for UFL to support complex functions,

I suggest rewriting your problem as a system of equations for the real
and imaginary parts, then just discretize using real numbers.

Hello,
    How would one go about implementing such structures? I too am
interested in using complex numbers, and finite fields would also be
useful. Is there any particular linear algebra package perhaps that might
be well suited to overwrite the basic addition and multiplication functions
of the matrix and vector elements?
    Thanks,
