I am wondering if there is or are any relationship among those. I have understood Markov Property by reading Wikipedia, but it is still confusing to figure out if there is any relationship among those three thing. I met Stationarity when I was studying Markov Chain and I met Time Invariance when I was studying Dynamic Bayesian Network. Markov Property was find to understand and stationarity was fine to understand in Markov Process, but I don't know if Time Invariance mean the same as Stationarity. Another thing that I also wonder is if there is any relationship between Markove Property and Time Invariance? Hope I am not confusing you.
