Unirational nonrational varieties Alexandra Kusnetsova National Research University "Higher School of Economics" (HSE), Moscow
Abstract: One example of unirational nonrational varieties is a double covering of $\mathbb P^3$ ramified in a nodal quartic. I am going to tell how we can study such coverings and how to prove that in a special case the covering is certainly nonrational. I will follow papers by Stephan Endrass.
