Stability of Halphen pencils of index two
nell'ambito della serie: SEMINARIO DI ALGEBRA E GEOMETRIA
algebra e geometria
In this talk I will present some results about the GIT stability of Halphen pencils of index two under the action of SL(3). These are pencils of plane curves of degree six having nine (possibly infinitely near) base points of multiplicity two. Inspired by the work of Miranda on pencils of plane cubics, I will explain how we can explore the geometry of the associated rational elliptic surfaces.
organizzato da: Jacopo Gandini, Antonella Grassi, Giovanni Mongardi nell'ambito del progetto TInGeCoRe "The Interplay of Geometry, Combinatorics and Representation Theory" (Bando Strutture 2020)
