Random Walks and Brownian Motion Lecture 2

چکیده

The following lecture will consider mainly the simple random walk in 1-dimension. The SRW will satisfy us for now as it can be generalized with a few simple assumptions to various other random walks. Our main topics are the Wald identities along with the derivation of the moment generating function of the first passage time for 1-dimensional SRW and the SRW properties such as: the arcsine laws for the last zero and fraction of time above axis, time reversal and equidistribution of positive time for SRW bridge. We will see that there are several properties whose probability distribution is similar asymptotically to the arcsine function.

Random Walks and Brownian Motion

Tags for today's lecture: Donsker's invariance priciple, Stochastic integration, Itô's formula In this lecture we show an application of Donsker's invariance principle and then proceed to the construction of Itô's stochastic integral. We recall the definitions and give a simple example of an application of the invariance principle. Consider a random walk S n = Σ n i=1 x i with E(x) = 0, E(x 2) ...

Lecture 3: From Random Walks to Continuum Diffusion

In the previous lecture (by Prof. Yip), we discussed how individual particles undergo complicated, apparently random motion, in a liquid or gas, which is termed “diffusion”. The same erratic motion due to collisions can be observed at the macroscopic scale in the so­called Brownian motion of a dust particle in the air. A simulation of this phenomenon (java applet), shown in lecture, can be foun...

Random Walks and Brownian Motion

In today’s lecture we present the Brownian motion (BM). We start with an intuitive discussion, describing the BM as a limit of SRW. We present some of the BM properties and try to explain why we can expect these properties from a limit of SRW. We then give a formal definition for BM and prove such a process exists (Wiener 1923). Before the proof we give some important facts about the normal dis...

A Simple Construction of the Fractional Brownian Motion

In this work we introduce correlated random walks on Z. When picking suitably at random the coefficient of correlation, and taking the average over a large number of walks, we obtain a discrete Gaussian process, whose scaling limit is the fractional Brownian motion. We have to use two radically different models for both cases 1 2 ≤ H < 1 and 0 < H < 1 2 . This result provides an algorithm for t...
