Reduced norm and reduced trace (1)

Throughout this post, is a field and is a finite dimensional central simple -algebra of degree

Let and suppose that is the characteristic polynomial of We know from linear algebra that and We also know that is -linear, is multiplicative and for all We’d like to extend the concepts of trace and determinant to any finite dimensional central simple algebra. 195 more words
