**1**. Markov matrix: Each column of P adds to **1**, so λ = **1** is an eigenvalue. 2. P is singular, so λ = 0 is an eigenvalue. 3. P is symmetric, so its eigenvectors (**1**,**1**) and (**1**,−**1**) are perpendicular. The only eigenvalues of a projection matrix are 0and **1**. The eigenvectors for λ = 0(which means Px = 0x)ﬁll up the nullspace.
