| Canonical Hilbert-Burch matrices for ideals of $k[x,y]$ (2007) | |||||||||
Abstract | |||||||||
| An Artinian ideal $I$ of $k[x,y]$ has many Hilbert-Burch matrices. We show that there is a canonical choice. As an application, we determine the dimension of certain affine Gr\"obner cells and their Betti strata recovering results of Ellingsrud and Str{\o}mme, G\"ottsche and Iarrobino. | |||||||||
