Allan> Allan Adler Allan> ara@altdorf.ai.mit.edu Allan, Primary decomposition can be accomplished using Grobner basis calculations. See a recent paper by Gianni and Trager (sorry, I don't have the reference handy. You might want to get in touch with Barry Trager about it: bmt@watson.ibm.com). I do know that these algorithms are included in the Axiom system. -- Victor S. Miller Vnet and Bitnet: VICTOR at WATSON Internet: victor@watson.ibm.com IBM, TJ Watson Research Center
