Tilting over commutative rings has for a long time been considered trivial, for in this case, there are no non-projective finitely generated tilting modules. But the picture changes completely once we broaden our horizons to infinitely generated modules. Not only that approximation theory and category equivalences are still available in this generality, but a complete classification is possible in many cases. In this talk, we will start by the relevant general results, and then deal in detail with the case of commutative noetherian rings.
