摘 要：The Topological Period-Index Problem (TPIP) is a topological variation of the long-standing period-index problem in algebraic geometry, which concerns an elementαof the Brauer group of (the function field of) a scheme X and various Azumaya algebras over X that representα. In this talk I will present an overview as well as the latest results on TPIP.
