Transcribed Image Text:1-α B
Show that every 2 x 2 stochastic matrix has at least one steady-state vector. Any such matrix can be written in the form P =
α 1-B
where x and ẞ are constants between 0 and 1. (There are two linearly independent steady-state vectors if a = ß= 0. Otherwise, there is
only one.)
If P is a stochastic matrix, then a steady-state vector, or equilibrium vector, for P is a probability vector q such that Pq=q.
If a =B=0, then P=

01
Notice that Px = x for any vector x in R². Determine two linearly independent steady-state vectors in this case.
