Д. Минеев: Семейство особых трёхмерных рациональных многообразий Фано степени 6 в $\mathbb P^5$; K. Hong: Factoriality of some nodal threefolds

D. Mineev. We will construct a birational map of a nodal cubic hypersurface containing a rational curve to the intersection of quadric and cubic with $16$ new double points.
K. Hong. I will talk about the factoriality of a nodal quartic hypersurface in $\mathbb P^4$ and a nodal quartic double solid.
