通过本课程学习,研究生能基本掌握随机过程的基本概念、基本理论与方法,并为完成毕业论文做好准备。
There are four chapters in stochastic processes.
1. basis of probability theory: conditional mathematical expectation, characteristic function, n-dimensional normal distribution.
2. basic concepts of stochastic processes: family of finite dimensional distribution functions, numerical characteristics of stochastic processes. normal process, process with independent increaments,Wiener process, Poisson process, renewal process.
3. Markov chain: discret-time Markov chains, classification of states, ergodic, stationary distribution. Continuous-time Markov chains, birth and death process.
4. stationary process: spectral decomposition of covariance function, spectral decomposition of stationary process, linear time invariant system, ergodic theorem, sampling theorem.
Students should muster the basic concept ,theory and methods of stochastic processes through studying this course. It is helpful for improving the students’ ability and it is beneficial for the their mathematic career.
