For example, if we look at quantum mechanics over a finite field $F$ (e.g. $\mathbb{Z}_2$), can this lead to new insights for "regular" quantum mechanics? Or do these toy models just help clarify our understanding of "regular" quantum mechanics without actually providing any new insight? In other words, what is the utility of having toy models of quantum mechanics?</p> http://mathoverflow.net/questions/53431/does-any-research-mathematics-involve-solving-functional-equations/53434#53434 Answer by PEV for Does any research mathematics involve solving functional equations?

I am interested in pursuing a PhD in math and making a career switch.
