Repeating eigenvalues
In this section we review the most relevant background on tensors and tensor fields. A 3D (symmetric) tensor T has three real-valued eigenvalues: λ 1 ≥ λ 2 ≥ λ 3.A tensor is degenerate if there are repeating eigenvalues. There are two types of degenerate tensors, corresponding to three repeating eigenvalues (triple degenerate) and two …General Solution for repeated real eigenvalues. Suppose dx dt = Ax d x d t = A x is a system of which λ λ is a repeated real eigenvalue. Then the general solution is of the form: v0 = x(0) (initial condition) v1 = (A−λI)v0. v 0 = x ( 0) (initial condition) v 1 = ( A − λ I) v 0. Moreover, if v1 ≠ 0 v 1 ≠ 0 then it is an eigenvector ...

The system of two first-order equations therefore becomes the following second-order equation: .. x1 − (a + d). x1 + (ad − bc)x1 = 0. If we had taken the derivative of the second equation instead, we would have obtained the identical equation for x2: .. x2 − (a + d). x2 + (ad − bc)x2 = 0. In general, a system of n first-order linear ...The exploration starts with systems having real eigenvalues. By using some recent mathematics results on zeros of harmonic functions, we extend our results to the case of purely imaginary and non-repeating eigenvalues. These results are used in Section 5 to establish active observability. It is shown that if an input is randomized, then the ...
Jun 7, 2018 · Dylan’s answer takes you through the general method of dealing with eigenvalues for which the geometric multiplicity is less than the algebraic multiplicity, but in this case there’s a much more direct way to find a solution, one that doesn’t require computing any eigenvectors whatsoever. Non-diagonalizable matrices with a repeated eigenvalue. Theorem (Repeated eigenvalue) If λ is an eigenvalue of an n × n matrix A having algebraic multiplicity r = 2 and only one associated eigen-direction, then the differential equation x0(t) = Ax(t), has a linearly independent set of solutions given by x(1)(t) = v eλt, x(2)(t) = v t + w eλt.

sum of the products of mnon-repeating eigenvalues of M . We now propose to use the set (detM;d(m) ), m= (1;:::::;n 1), to parametrize an n n hermitian matrix. Some notable properties of the set are:(a) An n nmatrix always has ndistinct eigenvalues. (F) (b) An n nmatrix always has n, possibly repeating, eigenvalues. (T) (c) An n nmatrix always has neigenvectors that span Rn. (F) (d) Every matrix has at least 1 eigenvector. (T) (e) If Aand Bhave the same eigenvalues, they always have the same eigenvectors. (F)We say an eigenvalue λ1 of A is repeated if it is a multiple root of the char acteristic equation of A; in our case, as this is a quadratic equation, the only possible case is when λ1 is a double real root. We need to find two linearly independent solutions to the system (1). We can get one solution in the usual way.

Uhlenbeck’s Theorem (1976): for “almost any” metric on a 2‐manifold , the eigenvalues of are non‐repeating. ... krew rh An eigenvalue that is not repeated has an associated eigenvector which is different from zero. Therefore, the dimension of its eigenspace is equal to 1, its geometric multiplicity is equal to 1 and equals its algebraic multiplicity. Thus, an eigenvalue that is not repeated is also non-defective. Solved exercises What if Ahas repeated eigenvalues?

If the set of eigenvalues for the system has repeated real eigenvalues, then the stability of the critical point depends on whether the eigenvectors associated with the eigenvalues are linearly independent, or orthogonal. This is the case of degeneracy, where more than one eigenvector is associated with an eigenvalue.
