Overview - Department of Mathematics

Overview This is an introduction to the mathematical foundations of probability theory. It is intended as a supplement or follow-up to a graduate course in real analysis. The rst two sections assume the knowledge of measure spaces, measurable functions, Lebesgue integral, and notions of convergence of functions; the third assumes ...

Random Walk: A Modern Introduction

Random walk – the stochastic process formed by successive summation of independent, identically distributed random variables – is one of the most basic and well-studied topics in probability theory. For random walks on the integer lattice Zd, the main reference is the classic book by Spitzer [16].

Stochastic Calculus: An Introduction with Applications

This is an introduction to stochastic calculus. I will assume that the reader has had a post-calculus course in probability or statistics. For much of these notes this is all that is needed, but to have a deep understanding of the subject, one needs to know measure theory and probability from that per-spective.

Chapter 4 Inverse Function Theorem

Indeed, in MATH2060 we learned that if f is continuously di erentiable on (a;b) with non-vanishing f0, it is either strictly increasing or decreasing so that its global inverse exists and is again continuously di erentiable. Example 4.3. Consider the map F: R2!R2 given by F(x;y) = (x2;y). Its Jacobian matrix is singular at (0;0).
