+"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, exceptional divisors,
+and real structure recorded in the homology of the covering K3-surface (this is a joint work with Alex Degtyarev).
