Stochastic Calculus I & II: Course Outline for Stochastic Calculus-II (MAT 646)

Stochastic calculus is a branch of mathematics that operates on stochastic processes. It allows a consistent theory of integration to be defined for integrals of stochastic processes with respect to stochastic processes.
