A matrix is diagonalizable, so what? - Mathematics Stack Exchange
4 I'll try an answer in a different (equivalent) direction: what happens when the matrix is not diagonalizable? First of all, this must mean that some of the matrix's eigenvalues occur more …
Show that if $A^ {n}=I$ then $A$ is diagonalizable.
Suppose $A$ is an $m \\times m$ matrix which satisfies $A^{n}=1$ for some $n$, then why is $A$ necessarily diagonalizable. Not sure if this is helpful, but here's my ...
matrices - Diagonalizable matrix with only one eigenvalue
Yes, it is possible for a matrix to be diagonalizable and to have only one eigenvalue; as you suggested, the identity matrix is proof of that. But if you know nothing else about the matrix, …
Any nonzero nilpotent matrix is not diagonalizable
Sep 2, 2024 · 15 I'm trying to go about the proof that any matrix that is nilpotent (i.e. $\exists N \in\Bbb N. A^N = \mathbf {0}$) cannot be diagonalizable. I believe that the best way to go …
Diagonalizable matrices with complex values are dense in set of $n ...
Diagonalizable matrices with complex values are dense in set of $n \times n$ complex matrices. He defined a metric (I believe) that was somehow related to the usual metric on $\mathbb {R}^ …
