Jordan form with -1 in block

42 Views Asked by At

I'm having troubles finding the right base, I keep getting a weird Jordan form.
I need to find the Jordan form and basis of $$ \left[\begin{array}{cc} 1 & 1\\ -1 & 3 \end{array}\right] $$
this leads me to $$ \left[\begin{array}{cc} \lambda-1 & -1\\ 1 & \lambda-3 \end{array}\right]=(\lambda-1)(\lambda-3)+1=(\lambda-2)^{2} $$ So now I calculate the eigenvectors for eigenvalue 2: $$ \begin{array}{cc|c} 1 & -1 & 0\\ 1 & -1 & 0 \end{array}\Rightarrow\begin{cases} x-y=0\\ x-y=0 \end{cases}\Rightarrow\left(\begin{array}{c} 1\\ 1 \end{array}\right) $$ Now after I found it I find the eigenvalue that chains to it and get : $$ \begin{array}{cc|c} 1 & -1 & 1\\ 1 & -1 & 1 \end{array}\Rightarrow\begin{cases} x-y=1\\ x-y=1 \end{cases}\Rightarrow\left(\begin{array}{c} 1\\ 0 \end{array}\right) $$ So now I have P=$$ \left(\begin{array}{cc} 1 & 1\\ 1 & 0 \end{array}\right)\Rightarrow P^{-1}=\left(\begin{array}{cc} 0 & 1\\ 1 & -1 \end{array}\right) $$ After multiplying $$P^{-1}AP=\begin{pmatrix}0&1\\ \:\:1&-1\end{pmatrix}\begin{pmatrix}1&1\\ \:\:-1&3\end{pmatrix}\begin{pmatrix}1&1\\ \:\:1&0\end{pmatrix}=\left(\begin{array}{cc} 2 & -1\\ 0 & 2 \end{array}\right) $$

Where did I go wrong? why is the Jordan form not $$ \left(\begin{array}{cc} 2 & 1\\ 0 & 2 \end{array}\right)? $$
