The orthogonality condition Ω µTJ · H t dx = 0 then insures that T lies in the range space of the (1,1) operator and therefore the saddle point system is nonsingular. When λt is a repeated eigenvalue, the null space of the (1,1) operator is of the dimension of the multiplicity of the repeated eigenvalue, and the system is no longer singular.However, the repeated eigenvalue at 4 must be handled more carefully.

This will include deriving a second linearly independent solution that we will need to form the general solution to the system. The three eigenvalues are not distinct because there is a repeated eigenvalue whose algebraic multiplicity equals two. However, the two eigenvectors and associated to the repeated eigenvalue are linearly independent because they are not a multiple of each other. As a consequence, also the geometric multiplicity equals two. 1.Compute the eigenvalues and (honest) eigenvectors associated to them.

Sinha [14, 15] has developed an algorithm to compute eigenvalues and eigenvectors of an undamped structure when eigenvalues are repeated. In this ... When there is a repeated eigenvalue, and only one real eigenvector, the trajectories must be nearly parallel to the eigenvector, both when near and when far from the fixed point.

If the matrix A is real and symmetric, the system was decoupled, and the solution is trivial. However, if we have only one linearly independent eigenvector (the matrix is defective), we must search for an additional solution. The general solution is given byIf you throw the zero vector into the set of all eigenvectors for $\lambda_1$, then you obtain a vector space, $E_1$, called the eigenspace of the eigenvalue $\lambda_1$. This vector space has dimension at most the multiplicity of $\lambda_1$ in the characteristic polynomial of $A$. Eigenvalues and eigenvectors prove enormously useful in linear mapping. Let's take an example: suppose you want to change the perspective of a painting.
