Résumé : In this session, I’ll talk about the problem of finding real inflection points in real algebraic projective curves in the real projective plane (4 realz). Tropical Geometry has proved to serve algebraic geometry by dealing with simpler, piecewise linear objects than its classical counterpart. I’ll mention some basics about tropical geometry and introduce a tropical version of a technique to build curves by ’sewing’ little pieces of curves together : patchworking. There will be drawings !!
