초록

We study the factoriality of a nodal quartic hypersurface $V_4$ in $\PP^4$ when there is a hyperplane in $\PP^4$ containing all the nodes of $V_4$. As an application, we obtain new examples of irrational quartic $3$-folds.

Abstract

We study the factoriality of a nodal quartic hypersurface $V_4$ in $\PP^4$ when there is a hyperplane in $\PP^4$ containing all the nodes of $V_4$. As an application, we obtain new examples of irrational quartic $3$-folds.
