Tropical Methods in Real Algebraic Geometry

The "Tropical Methods in Real Algebraic Geometry" workshop is organized at Universidad Nacional Autonoma de Mexico

The Casa Matemática Oaxaca (CMO) will host the "Tropical Methods in Real Algebraic Geometry" workshop in Oaxaca, from September 8, 2019 to September 13, 2019.

Tropical methods provide an extremely powerful new set of tools in the study of complex and real algebraic geometry. Among the branches of real algebraic geometry that have benefited from these tools are the construction of real algebraic varieties with controlled topology, and also real enumerative geometry. One of the roots of tropical geometry lies in Viro's patchworking invented in the late seventies to construct real algebraic varieties with a rich topology. Applications of tropical methods to real and complex enumerative geometry were initiated by Mikhalkin's seminal Correspondence Theorem in the early 2000. In particular, it supplied at that time the first method to compute Welschinger invariants of del Pezzo real toric surfaces. In recent years, new real, complex, and tropical enumerative invariants have been discovered. Computing and relating all these invariants is one of the current leading research directions in this field.

Claus Scheiderer from Univ. Konstanz, Germany, a beneficiary in POEMA is present at the workshop.
