hi here is the question and i don't know how to solve it.
a transition matrix P is called doubly stochastic if not only its rows sum up to one, but also its columns. In exact terms, P=(pij) which i,j is the elements of E is called doubly stochastic if
pij is greater or equal to 0 and the sum of pik=1 and the sum of pkj=1
for all i,j elements E.
and X=(Xn:n is elements of natural number) be an irreducible homogeneous Markov chain with a doubly stochastic transition matrix P. Assume that the state space E is finite. Determine the stationary distribution for X.
So how could i actually solve this question?please help and many thanks.
