Graph hypersurfaces with torus action and a conjecture of Aluffi
Graham Denham, Delphine Pol, Mathias Schulze +1
Generalizing the star graphs of Müller-Stach and Westrich, we describe a class of graphs whose associated graph hypersurface is equipped with a non-trivial torus action. For such g…

On Constructions of Free Singularities
Raul Epure, Delphine Pol
The purpose of this paper is to give new examples of families of free singularities. We first show that a generic equidimensional subspace arrangement is free. Furthermore, we show…
