Throughout we use the following notation for the real numbers the nonnegative real numbers the integers and the nonnegative integers respectively IR def 1 IR def 0 2 def 575275752757527 3 IN def 575275752757527 4 11 Normal distribution Of part e shall con sider a subset of particles such as a dissolved solute or a suspension characterized by a number density 1 that in general depends on position and time The flux of particles across a plane perpendicular to the axis is the number density 5 An Introduction to Stochastic Processes and Applications. 5.1.1 Stochastic . Processes: A Brief Introduction. A . stochastic process. is a sequence of random variables . X. t. defined on a common probability space (. Stochastic Calculus: Introduction . Although . stochastic . and ordinary calculus share many common properties, there are fundamental differences. The probabilistic nature of stochastic processes distinguishes them from the deterministic functions associated with ordinary calculus. Since stochastic differential equations so frequently involve Brownian motion, second order terms in the Taylor series expansion of functions become important, in contrast to ordinary calculus where they can be ignored. .

Generally the time period is from 0 to T. . During this time, events may be happening at various points along the way that may have an effect on the eventual value of the process. .
