Dimension of an eigenspace.

Therefore, (λ − μ) x, y = 0. Since λ − μ ≠ 0, then x, y = 0, i.e., x ⊥ y. Now find an orthonormal basis for each eigenspace; since the eigenspaces are mutually orthogonal, these vectors together give an orthonormal subset of Rn. Finally, since symmetric matrices are diagonalizable, this set will be a basis (just count dimensions).2 Answers. The algebraic multiplicity of λ = 1 is 2. A matrix is diagonalizable if and only if the algebraic multiplicity equals the geometric multiplicity of each eigenvalues. By your computations, the eigenspace of λ = 1 has dimension 1; that is, the geometric multiplicity of λ = 1 is 1, and so strictly smaller than its algebraic multiplicity.equal to the dimension of the eigenspace corresponding to .
