So 2 repeated eigenvalues means 1 unique unit eigenvector and an entire plane of linearly independent eigenvectors.almu( 1) = 1. Strictly speaking, almu(0) = 0, as 0 is not an eigenvalue of Aand it is sometimes convenient to follow this convention. We say an eigenvalue, , is repeated if almu( ) 2. Algebraic fact, counting algebraic multiplicity, a n nmatrix has at most nreal eigenvalues. If nis odd, then there is at least one real eigenvalue.
