SIMILAR MATRICES Similar Matrices - Mathematics

are similar to diagonal matrices are extremely useful for computing large powers of the matrix. As such, it is natural to ask when a given matrix is similar to a diagonal matrix. We have the following complete answer: Theorem 3.1. A matrix Ais similar to a diagonal matrix if and only if there is an ordered basis B= (~v

Lemma 0.27: Composition of Bijections is a Bijection

Lemma 0.27: Composition of Bijections is a Bijection Jordan Paschke Lemma 0.27: Let A, B, and C be sets and suppose that there are bijective correspondences between A and B, and between B and C. Then there is a bijective correspondence between A and C. Proof: Suppose there are bijections f : A !B and g : B !C, and de ne h = (g f) : A !C. We will

Subspaces - Mathematics

The Subspace Test To test whether or not S is a subspace of some Vector Space Rn you must check two things: 1. if s 1 and s 2 are vectors in S, their sum must also be in S 2. if s is a vector in S and k is a scalar, ks must also be in S In other words, to test if a set is a subspace of a Vector Space, you only need to check if it closed under ...
