A stochastic or random process can be defined as a collection of random variables that is indexed by some mathematical set, meaning that each random variable of the stochastic process is uniquely associated with an element in the set. For brevity we will always use the term stochastic process, even if we talk about random vectors rather than random variables. Introduction This first lecture outlines the organizational aspects of the class as well as its contents. Chapter 1 Random walk 1.1 Symmetric simple random walk Let X0 = xand Xn+1 = Xn+ n+1: (1.1) The i are independent, identically distributed random variables such that P[i = 1] = 1=2.The probabilities for this random walk also depend on x, and we shall denote them by Px.We can think of this as a fair gambling If you have watched this lecture and know what it is about, particularly what Mathematics topics are discussed, please help us by commenting on this video with your suggested description and title.Many thanks from, stochastic processes : lecture number 4 : chapter 2 of lecture notes: Poisson Process: Axioms and Construction : lecture number 5 : .

The mathematical theory of stochastic processes regards the instantaneous state of the system in question as a point of a certain phase space $ R $( the space of states), so that the stochastic process is a function $ X ( t) $ of the time $ t $ with values in $ R $.

Each vertex has a random number of offsprings. Stochastic processes A stochastic process is an indexed set of random variables Xt, t T i.e. A stochastic process is defined as a collection of random variables X= {Xt:tT} defined on a common probability space, taking values in a common set S (the state space), and indexed by a set T, often either N or [0, ) and thought of as time (discrete or continuous respectively) (Oliver, 2009).
