The enumerative geometry of cubic hypersurfaces: point and line conditions

Mara Belotti, Alessandro Danelon, Claudia Fevola +1

In order to count the number of smooth cubic hypersurfaces tangent to a prescribed number of lines and passing through a given number of points, we construct a compactification of…

The Chow ring of hyperkähler varieties of $K 3^{[2]}$ -type via Lefschetz actions

Andreas Kretschmer

We propose an explicit conjectural lift of the Neron-Severi Lie algebra of a hyperkähler variety $X$ of $K 3^{[2]}$ -type to the Chow ring of correspondences ${\rm CH}^\ast(X \times…
