Class for a parallel sesquilinear form
A sesquilinear form is a generalization of a bilinear form to complex-valued fields. Sesquilinear forms are linear in the second argument but the first argument involves a complex conjugate in the sense that:
a(alpha u, beta v) = conj(alpha) beta a(u, v)
The convention argument in the class's constructor is documented in the mfem::ComplexOperator class found in linalg/complex_operator.hpp.
When supplying integrators to the ParSesquilinearForm either the real or imaginary integrator can be NULL. This indicates that the corresponding portion of the complex-valued material coefficient is equal to zero.

Create a ParSesquilinearForm on the ParFiniteElementSpace pf, using the same integrators as the ParBilinearForms pbfr and pbfi .
The pointer pf is not owned by the newly constructed object.
The integrators are copied as pointers and they are not owned by the newly constructed ParSesquilinearForm.
