Abstract:
For two polynomials $G(X)$, $H(Y)$ with rational coefficients, when does $G(X) = H(Y)$ have infinitely many solutions over the rationals? Such $G$ and $H$ have been classified in various special cases by previous mathematicians. I will discuss both the known results, the new results in my thesis, and related problems which have yet to be solved.
