Suppose either that you need a proof of a statement which you believe to be true, or that you need a translation of your problem into precise equations. I would think about this and see if I can solve it for you.

Historically this has meant mostly the analysis of certain situations that appear in the applications of linear algebra. I am quite familiar with tensors and sparse matrices. I have also helped with equations for an analytic geometry problem. For the latter kind of problem I employ a powerful Gröbner basis method.
