Definition: the geometric multiplicity of an eigenvalue is … WebA has two different eigenvalues. In this case, each eigenvalue has algebraic and geometric multiplicity equal to one. This implies A is diagonalizable. For example: A = K 17 02 L . A has one eigenvalue λ of algebraic and geometric multiplicity 2. WebGeneralized Eigenvectors This section deals with defective square matrices (or corresponding linear transformations). Recall that a matrix A is defective if it is not diagonalizable. In other words, a square matrix is defective if it has at least one eigenvalue for which the geometric multiplicity is strictly less than its algebraic multiplicity. sherbourne caravan
