Yairon Cid Ruiz (MPI MIS, Leipzig): Rational maps, syzygies and specialization

Ort: MPI für Mathematik in den Naturwissenschaften Leipzig, Inselstr. 22, G3 10 (Hörsaal)

The idea of studying rational maps by looking at the syzygies of the base ideal is a relatively new idea that has now become an important research topic. In this talk, we will discuss some recent results that lead to birationality criteria and formulas for the degree of rational maps that depend on the algebraic properties of the syzygies of the base ideal. In a related way, we will also discuss some results in the problem of specializing the coefficients of a rational map.
