By breaking down differentiation and integration into digestible concepts, this guide helps you build a stronger foundation with a solid understanding of the big ideas at work. Is also used to denote the Stratonovich integral.Īn important application of stochastic calculus is in mathematical finance, in which asset prices are often assumed to follow stochastic differential equations.

Slay the calculus monster with this user-friendly guide Calculus For Dummies, 2nd Edition makes calculus manageableeven if youre one of the many students who sweat at the thought of it.
Sam used Differential Calculus to cut time and distance into such small pieces that a pure answer came out.
Integral Calculus joins (integrates) the small pieces together to find how much there is. Differential Calculus cuts something into small pieces to find how it changes. The Stratonovich integral or Fisk–Stratonovich integral of a semimartingale X It provides discrete explanations of critical concepts taught in a typical two-semester high school calculus class or a college level Calculus I course. The word Calculus comes from Latin meaning 'small stone'. The dominated convergence theorem does not hold for the Stratonovich integral consequently it is very difficult to prove results without re-expressing the integrals in Itô form. This enables problems to be expressed in a coordinate system invariant form, which is invaluable when developing stochastic calculus on manifolds other than R n. The main benefit of the Stratonovich integral is that it obeys the usual chain rule and therefore does not require Itô's lemma.
The Stratonovich integral can readily be expressed in terms of the Itô integral. For technical reasons the Itô integral is the most useful for general classes of processes, but the related Stratonovich integral is frequently useful in problem formulation (particularly in engineering disciplines). The main flavours of stochastic calculus are the Itô calculus and its variational relative the Malliavin calculus.

Since the 1970s, the Wiener process has been widely applied in financial mathematics and economics to model the evolution in time of stock prices and bond interest rates. The best-known stochastic process to which stochastic calculus is applied is the Wiener process (named in honor of Norbert Wiener), which is used for modeling Brownian motion as described by Louis Bachelier in 1900 and by Albert Einstein in 1905 and other physical diffusion processes in space of particles subject to random forces. This field was created and started by the Japanese mathematician Kiyosi Itô during World War II. It allows a consistent theory of integration to be defined for integrals of stochastic processes with respect to stochastic processes.
