Ornella Greco: Betti numbers of Veronese modules
Tid: On 2015-01-28 kl 13.15 - 14.15
Plats: Room 306, Kräftriket, SU
Medverkande: Ornella Greco, KTH
In this talk, I will concentrate on the minimal free resolution of the Veronese modules, and I will give a formula for their Betti numbers in terms of the reduced homology of some skeleton of a simplicial complex. As applications, I will characterize their Cohen-Macaulayness and the linearity of their resolution. Moreover, I will give a complete description of the Betti table of all the Veronese modules in 2 variables.
