<div><h1>Elimination -- eliminating specified variables, and Sylvester resultant</h1>
<div class="single"><h2>Description</h2>
<div>This package contains functions to eliminate variables from an ideal (that is, intersect an ideal with a subring generated by certain of the variables), and to compute Sylvester resultants.<p>It would be nice to implement multivariate resultants, Bezoutians, and sparse resultants. Laurent Buse has written code for this in the past. We hope to provide a package, Resultants, which will do this. If you are willing to help write this, please contact the author if this package!</p>
