Question 5. Let A ? Rn×n be a stochastic matrix. Use the fact that A is stochastic, i.e., all columns sum to one, to demonstrate that A must have an eigenvalue ? = 1. Question 6. Let $\begin{bmatrix} r & s & t \\ 0 & u & v \\ 0 & 0 & w \end{bmatrix}$ ? R3×3 b = $\begin{pmatrix} x \\ y \\ z \end{pmatrix}$ ? R3. We know that the system b = Ax, for x ? R3, has (a) a unique solution, (b) infinitely many solutions, or (c) no solutions. Give conditions on r, s,..., z ? R so that the system b = Ax has (a) a unique solution, (b) infinitely many solutions, or (c) no solutions.
