+ | "Basic algebra and algebraic geometry special talk: | ||
+ | Real plane sextic curves without real singular points" | ||
+ | |||
+ | We will start with a brief introduction to topology of real algebraic curves, | ||
+ | and then will discuss in more details the case of curves of degree 6 in the real projective plane. | ||
+ | We will prove that the equisingular deformation type of a simple real plane sextic curve | ||
+ | with smooth real part is determined by its real homological type, that is, the polarization, | ||
+ | and real structure recorded in the homology of the covering K3-surface (this is a joint work with Alex Degtyarev). | ||
