RadicalOfUnmixed
Syntax
RadicalOfUnmixed(I:IDEAL):IDEAL
Summary
radical of an unmixed ideal
Description
This function computes the radical of an unmixed ideal.

NOTE: at the moment, this implementation works only if the coefficient
ring is the rationals or has large enough characteristic.

Example

Use R ::= Q[x,y];
I := Ideal(x^2 - y^2 - 4x + 4y, x - 2);
-------------------------------
RadicalOfUnmixed(I);
Ideal(x^2 - y^2 - 4x + 4y, x - 2, y - 2)
-------------------------------
Minimalized(It); -- the result may not be presented in its simplest form
Ideal(x - 2, y - 2)
-------------------------------
