Hello all, This is my first post here and so I hope I am posting in the appropriate section. My question is actually related to both Physics and Discrete Mathematics. I'm writing a very general essay (no rigorous derivations or extremely involved mathematics) about Markov chains as they are applied to cosmology. I've spend the past 3 or 4 hours pouring over the resources offered by my college's library as well as those offered by the internet. Sadly, this search hasn't yielded too much. I found a few papers on Markov Chain Monte Carlo methods, but these papers tend to get very detailed, complicated, and long. The main question I have for all of you helpful folks making up these forums is where I can go to find information on the basics of Markov Chains and how they are applied to cosmology. Do you have any papers or authors to suggest? Perhaps a relatively common book? Websites will also work. I just haven’t been able to find many good sources. Also, my professor mentioned that there is a debate about whether or not Markov Chains/Discrete methods are applicable to cosmology due to the fact that the universe may or may not be a physical realization of infinity. If anyone knows where I could find resources on such a debate, it would be greatly appreciated. I have been unable to find anything other than vague hints at such a debate in my search for sources. That about sums up my requests. Thanks in advance to all those that help/provide sources of information.
