Let
, and let
be a polynomial. Show that if is an
eigenvalue of , then is an
eigenvalue of .
Hint: this follows from the more precise statement that if
is a
non-zero eigenvector for for the eigenvalue
, then is also an
eigenvector for for the
eigenvalue . Prove
this.

(b) Explain why satisfies the conditions of the martingale convergence theorem (c) Let . Explain why (Hint: there are at least two ways to show this. One is to consider and use the law of large numbers. Another is to note that with probability one does not converge) (d) Use the optional sampling theorem to determine the probability that ever attains...
