The research field is Markov process; The phase transition and critical phenomena of infinite particle systems on trees and graphs are studied. The metastability of stochastic Ising model is characterized and extended to a family of Markov chains with exponential perturbation; The large deviation theory is introduced to make the treatment method unified and concise, and the application scope is wider; The random walk in random environment is studied, and the upper and lower bounds of the velocity of the random walk are obtained; It is proved that the conclusion that the velocity of random walk is zero remains unchanged under random disturbance.
