WebJan 24, 2024 · This matrix is called the Smith normal form of $ A $. The $ d _ {i} $ are called the invariant factors of $ A $ and the number $ r $ is called its rank. The Smith normal form of $ A $ is uniquely determined and can be found as follows. The rank $ r $ of $ A $ is the order of the largest non-zero minor of $ A $. Suppose that $ 1 \leq j \leq r ... Weband the polynomials ai(x) are the invariant factors of T. By Lemma M.6.2, there is a basis of Vi such that the matrix of Ti with respect to this basis is the companion matrix of ai(x). Therefore, there is a basis of V with respect to which the matrix of T is in rational canonical form. Now suppose that the matrix A of T with respect to some basis
