Resolutions of ideals of any six fat points in P2

[摘要] The graded Belli numbers of the minimal free resolution (and also therefore the Hilbert function) of the ideal of a fat point subscherne Z of P-2 are determined whenever Z is supported at any 6 or fewer distinct points. All results hold over an algebraically closed field k of arbitrary characteristic. (c) 2007 Elsevier Inc. All rights reserved.
