Author: David Kohel, 2005-09
Class: QuaternionOrderElement
self, A, x, [check=True]) |
Create the element x of the quaternion order A.
Functions: characteristic_polynomial,
charpoly,
conjugate,
minimal_polynomial,
minpoly,
reduced_norm,
reduced_trace,
vector
self) |
Return the reduced trace of this element.
Note:
In a quaternion algebra
, every element
is
quadratic over the center, thus
, so
we solve for a linear relation
among
for the reduced trace of
.
