We can understand g as a function of the eigenvalues of L, i.e. g () . Evaluating Eq. 3 is computationally expensive, as multiplication with the eigenvector ...

staff.imsa.eduMultiplicity of Eigenvalues Learning Goals: to see the difference between algebraic and geometric multiplicity. We have seen an example of a matrix that does not have a basis’ worth of eigenvectors. For example. 11 01 ⎡ ⎣ ⎢ ⎤ ⎦ ⎥ (note: this is not the Fibonacci matrix!). The characteristic polynomial of
