# Limit set of a linear dynamical system [closed]

I would like to find the limit set $\omega(x)$ of the linear dynamical system

$$\mathrm f (x_1, x_2) = \begin{bmatrix} 2 & 1\\ 1 & 1\end{bmatrix} \begin{bmatrix} x_1\\ x_2\end{bmatrix}$$

I tried a few numerical values of $x_1$ and $x_2$ to see the sequence of vectors, but I'm not sure if this is right. I would appreciate your help.

• The matrix is positive definite. What can you conclude from that? – Rodrigo de Azevedo May 11 '17 at 12:18
• that all points are inside the omega limit set? – john May 11 '17 at 12:28

• thank you, Ali Taghavi, though I learn from examples, and my lecturer gave me this example but I don't understand. – john May 11 '17 at 14:16
