I will discuss how tame geometry can be used to prove algebraization results, either starting from diophantine informations (Pila-Wilkie theorem) or in a complex analytic setting (Chow and GAGA theorems in definable complex analytic geometry: results of Peterzil-Starchenko and Bakker-Brunebarbe-Tsimerman). Speaker(s): Bruno Klingler (Humboldt University)
