Let P be the transition matrix of a finite, irreducible and reversible Markov chain. We say the continuous time Markov chain X has transition matrix P and speed λ if it jumps at rate λ according to the matrix P . Fix λX , λY , λZ ≥ 0, then let X,Y and Z be independent Markov chains with transition matrix P and speeds λX , λY and λZ respectively, all started from the stationary distribution. Wha...
