Let f be a function in H, a Hilbert space of analytic functions over a fixed domain. The function $f$ is called cyclic if the polynomials times $f$ form a dense subspace of H. A classical theorem by Brown and Shields classifies cyclicity when f is a polynomial in Dirichlet-type spaces over the unit disc. In this talk, we show the corresponding classifications of polynomials for Dirichlet-type spaces over the bidisc (and depending on time, also for weighted Hardy spaces over the unit disc).
