Corrado Segre and Nodal Cubic Threefolds

We discuss the work of Corrado Segre on nodal cubic hypersurfaces with emphasis on the cases of 6-nodal and 10-nodal cubics. In particular we discuss the Fano surface of lines and conic bundle structures on such threefolds. We review some of the modern research in algebraic geometry related to Segre’s work.

One way to improve upon these optimality results is by allowing the players to move sequentially. With this in mind, we study here a sequential version of the Bailey-Cavallo ...
