Abstract
AbstractLet L be a separable quadratic extension of either $${\mathbb {Q}}$$
Q
or $${\mathbb {F}}_q(t)$$
F
q
(
t
)
. We exhibit efficient algorithms for finding isomorphisms between quaternion algebras over L. Our techniques are based on computing maximal one-sided ideals of the corestriction of a central simple L-algebra.
