A Chain Rule for Multivariable Resultants
A Chain Rule for Multivariable Resultants
We present a chain rule for the multivariable resultant, which is similar to the familiar chain rule for the Jacobian matrix.Specifically, given two homogeneous polynomial maps K" -» K" for a commutative ring K, such that their composition is a homogeneous polynomial map, the resultant of the composition is the …
