FRIAS Project

Geometric structures on algebraic varieties

The project lies within algebraic geometry. It is a part of mathematics that deals with solutions of systems of polynomial equations. However, its methods have applications in many other areas of mathematics and mathematical physics. The project proposal lies on the border of some of these areas and it is concerned with geometry of algebraic varieties and geometric structures on such varieties.
