The Gram-Schmidt process does not change the span. Since the span of the two eigenvectors associated to $\lambda=1$ is precisely the eigenspace corresponding to $\lambda=1$, if you apply Gram-Schmidt to those two vectors you will obtain a pair of vectors that are orthonormal, and that span the eigenspace; in particular, they will also be eigenvectors associated to $\lambda=1$.

In short, what we find is that the eigenvectors of \(A^{T}\) are the “row” eigenvectors of \(A\), and vice–versa. [2] Who in the world thinks up this stuff? It seems that the answer is Marie Ennemond Camille Jordan, who, despite having at least two girl names, was a guy.In this case, V is a generalized eigenspace Va (a) of every a2h, so we just need to check the linearity of . Since h is nilpotent, it is solvable. Since we assumed F to be algebraically closed and with char-acteristic 0, we can then apply Lie’s theorem, which guarantees the existence of a weight 0with some nonzero weight space Vh 0.

Also, to apply the first comment, the number of …Step 2: The associated eigenvectors can now be found by substituting eigenvalues $\lambda$ into $(A − \lambda I)$. Eigenvectors that correspond to these eigenvalues are calculated by looking at vectors $\vec{v}$ such that Watch on. We’ve talked about changing bases from the standard basis to an alternate basis, and vice versa.
