Jakob Stix

Jakob M. Stix (born in 1974) is a German mathematician. He specializes in arithmetic algebraic geometry (étale fundamental group, anabelian geometry and other topics).

Stix studied mathematics in Freiburg and Bonn and received his doctorate in 2002 from Florian Pop at the University of Bonn (Projective Anabelian Curves in Positive Characteristic and Descent Theory for Log-Etale Covers ). His dissertation was awarded the best doctoral thesis of the year 2002 by the Mathematical Institute of the University of Bonn. He was a post-doctoral student at the Institute for Advanced Study. In 2008, he became junior research group leader at the Mathematics Center of the University of Heidelberg, where he habilitated in 2011 (Evidence for the section conjecture in the theory of arithmetic fundamental groups). Stix is now a professor at the University of Frankfurt.

He recently discovered and contributed to the solution of an error in an influential 1997 paper by Lucia Caporaso, Joe Harris and Barry Mazur on the implications of the strong Lang conjecture ("Uniformity of rational points". J. Amer. Math. Soc.,101-5 (1997))
