Description

The CoCoAManual entry for radical looks to be out of date.

It does not mention radical(RINGELEM) and also states that radical does not work over small finite char.

History

#1 Updated by John Abbott almost 7 years ago

The following output is surprising (though correct)

use ZZ/(3)[x,y];
radical(ideal(x^3+y^3));
---> ideal(x +y,  x +y)

added example for radical(poly).

I'm not confident it always works for ideals in small characteristic.
I hope the situation will be clearer with Alice Moallemy's conversion to C++.
