Then, it should be clear that the determinant of. has a factor of , which would contradict your assumption. Jul 7, 2008. $\begingroup$ You don't need to know anything about dimensions to show that any finite dimensional space decomposes as a direct sum of generalised eigenspaces. This depends only on the fact that the minimal polynomial splits, as it does over$~\Bbb C$, after which the primary decomposition theorem can be applied. $\endgroup$So, suppose the multiplicity of an eigenvalue is 2. Then, this either means that there are two linearly independent eigenvector or two linearly dependent eigenvector. If they are linearly dependent, then their dimension is obviously one. If not, then their dimension is at most two. And this generalizes to more than two vectors.I have to find out if A is diagonalizable or not. Also I have to write down the eigen spaces and their dimension. For eigenvalue, λ = 1 λ = 1 , I found the following equation: x1 +x2 − x3 4 = 0 x 1 + x 2 − x 3 4 = 0. Here, I have two free variables. x2 x 2 and x3 x 3..
