WebSyzygyData. A central open question in the study of syzygies is to describe the Betti table of Pn P n under the degree d d Veronese embedding. While the case when n=1 n = 1 is fully understood and classical — the minimal resolution is given by an Eagon-Northcott complex — in higher dimensions this problem is almost entirely open. WebThe Eagon-Northcott complex is an explicit chain complex that gives a minimal projective resolution of the cokernel of the matrix maximal minors of a generic matrix of linear forms.
