取任意一个的可分离二次扩展。我们展示了有效的算法来寻找四元数代数之间的同构。我们的技术是基于计算中心简单代数共约束的最大单侧理想。
LetLbe a separable quadratic extension of eitheror. We exhibit efficient algorithms for finding isomorphisms between quaternion algebras overL. Our techniques are based on computing maximal one-sided ideals of the corestriction of a central simpleL-algebra.
