Di Erential Calculus

A Brief Introduction to Stochastic Calculus

integrals and stochastic di erential equations. We will of couse also introduce It^o’s Lemma, probably the most important result in stochastic calculus. 1 Martingales, Brownian Motion and Quadratic Variation We make the following assumptions throughout. There is a probability triple (;F;P) where { Pis the \true" or physical probability measure {

7.4 Cauchy-Euler Equation - University of Utah

The di erential equation a nx ny(n) + a n 1x n 1y(n 1) + + a 0y = 0 is called the Cauchy-Euler di erential equation of order n. The sym-bols a i, i = 0;:::;n are constants and a n 6= 0. The Cauchy-Euler equation is important in the theory of linear di er-ential equations because it has direct application to Fourier’s method
