What if Ahas repeated eigenvalues? Assume that the eigenvalues of Aare: λ 1 = λ 2. •Easy Cases: A= λ 1 0 0 λ 1 ; •Hard Cases: A̸= λ 1 0 0 λ 1 , but λ 1 = λ 2. Find Solutions in the Easy Cases: A= λ 1I All vector ⃗x∈R2 satisfy (A−λ 1I)⃗x= 0. The eigenspace of λ 1 is the entire plane. We can pick ⃗u 1 = 1 0 ,⃗u 2 = 0 1 ...A = [ 3 0 0 3]. 🔗. A has an eigenvalue 3 of multiplicity 2. We call the multiplicity of the eigenvalue in the characteristic equation the algebraic multiplicity. In this case, there also exist 2 linearly independent eigenvectors, [ 1 0] and [ 0 1] corresponding to the eigenvalue 3. 10.5: Repeated Eigenvalues with One Eigenvector. Example: Find the general solution of x˙1 = x1 −x2,x˙2 = x1 + 3x2 x ˙ 1 = x 1 − x 2, x ˙ 2 = x 1 + 3 x 2. The ansatz x = veλt x = v e λ t leads to the characteristic equation. 0 = det(A − λI) = λ2 − 4λ + 4 = (λ − 2)2. 0 = det ( A − λ I) = λ 2 − 4 λ + 4 = ( λ − 2) 2.For each eigenvalue i, we compute k i independent solutions by using Theorems 5 and 6.
