# Multilinear eigenvalue problem

I'm trying to do something that requires solving an eigenvalue problem of the form
$$A_{imkl} c_m c_k c^*_l=\lambda c_i$$
where A is a known rank-4 tensor, $\lambda$ is the eigenvalue, and the $c_i$'s are a set of unknown coefficients that I need to determine. I would guess that this type of problem should be solvable, but I have no idea where to start. For all I know, it's a problem with a common name that I just don't know. Any pointers?

If anyone even knew what this class of problem is called, that would be tremendously helpful. (A Google search on various terms related to "eigenvalues" comes up with a lot of useless results.)
