2 The Adjoint of a Linear Transformation We will now look at the adjoint (in the inner-product sense) for a linear transformation. A self-adjoint linear transformation has a basis of orthonormal eigenvectors v 1,...,v n. Earlier, we deﬁned for T: V → W the adjoint T b: W∗ → V∗. If V and W are inner productrank as A (the proof of this statement is left to you; hint: linear transformation and C has an inverse). Then, the lemma follows from the fact that both P and P 1 have rank n. Lemma 2. If A and B are similar, then their characteristic equations imply each other; and hence, A and B have exactly the same eigenvalues. 1Unit 2: Matrix transformations.
