(Rational canonical form) Let T be a linear transformation of a ﬁnite dimensional vector space V over a ﬁeld K . (a) There is an ordered basis of V with respect to which the matrix of T is in rational canonical form. (b) Only one matrix in rational canonical form appears as the matrix of T with respect to some ordered basis of V . Proof. According to Theorem 8.5.16 , .T;V / has a direct sum decomposition .T;V / D .T 1 ;V 1 / ˚ ³³³ ˚ .T s ;V s /;...
