WebTheorem 3 part b says that for symmetric matrices, the dimension of each eigenspace equals the algebraic multiplicity of the corresponding eigenvalue. Therefore, the dimension of each eigenspace is never less than the multiplicity of the corresponding eigenvalue for a symmetric matrix. WebLet / denote a unit matrix. THEOREM 1. (Gantmacher [2], page 8, Theorem 4.) If two complex symmetric matrices are similar, then they are orthogonally similar. It follows that a complex symmetric matrix is diagonalisable by a simi-larity transformation when and only when it is diagonalisable by a (complex) orthogonal transformation.
