Canonical Hilbert-Burch matrices for power series

Roser Homs Pons and Anna-Lena Winz

Abstract

We give a parametrization of zero-dimensional ideals in the power series ring $k[[x,y]]$ with a given leading term ideal with respect to local lex ordering in terms of certain canonical Hilbert-Burch matrices. This is an extension to the local setting of the parametrizations of Gröbner cells obtained in the polynomial ring $k[x,y]$ by Conca and Valla for lex ordering and Constantinescu for deglex.
