I'm doing research on Google Matrix and PageRank algorithm. In a paper, there are terms that I'm unaware of, such as stationary distribution, stochastic matrix, convex combination, markov matrix, power method, perturbation bounds... If I want to know more about there, which concept of mathematics is it?
These are related to random walks or generally stochastic processes. A good book about it for the beginning: Rick Durrett - Essentials of Stochastic Processes
