Description: |
Given a pair of n-by-n zero/nonzero patterns for two matrices,
how can we tell when they admit a commuting pair. A number of
interesting questions are of this form, and thoughts about it lead to
many interesting questions. Like other qualitative matrix theoretic
questions, this one has to do, in the end, with the solvability of
certain systems of bilinear equations. We illustrate the connection
and give some recent results about solution theory for bilinear
systems.
