4. Is There A Steady State?
So far, we've seen that for a conservative state transition matrix A, we can find the eigenvector, v, corre-
sponding to the eigenvalue 2 = 1. This vector is the steady state since Av = v. However, we've so far taken
for granted that the state transition matrix even has the eigenvalue 1 = 1. Let's try to prove this fact.
(a) Show that if 2 is an eigenvalue of a matrix A, then it is also an eigenvalue of the matrix A".
Hint: The determinants of A and A' are the same. This is because the volumes which these matrices
represent are the same.
