Matrices theorems
WebTheorem . If A and B are matrices with real entries and A = PBP¡ 1for some matrix P with complex entries then A = QBQ¡ 1for some matrix Q with real entries. CONTENTS 3 The existence and uniqueness of the Jordan canonical form (VÄaliacho's simple proof). The real Jordan canonical form. 12.5.1. Theorem . WebSimilar matrices represent the same linear map under two (possibly) different bases, with P being the change of basis matrix.. A transformation A ↦ P −1 AP is called a similarity transformation or conjugation of the matrix A.In the general linear group, similarity is therefore the same as conjugacy, and similar matrices are also called conjugate; …
