In quantitative finance, the theory is known as Ito Calculus. The main use of stochastic calculus in finance is through modeling the random motion of an asset price in the Black-Scholes model. The physical process of Brownian motion (in particular, a geometric Brownian motion) is used as a model of asset prices, via the Weiner Process.

When I first read about it, it seemed like there were two mathematical treatments of the same physical process that give different answers. Professor Kiyosi Ito is well known as the creator of the modern theory of stochastic analysis. Although Ito first proposed his theory, now known as Ito's stochastic analysis or Ito's stochastic calculus, about fifty years ago, its value in both pure and applied mathematics is becoming greater and greater. For almost all modern theories at the forefront of probability and related fields, Ito's Lecture 11: Ito Calculus Wednesday, October 30, 13.

From Scholarpedia Kyoto, Japan. Dr. Kiyoshi Ito accepted the invitation on 9 March 2007. 1 Jun 2015 Definition - multidimensional Itô Integral. Let B(t, ω)=(B1(t, ω),, Bn(t, ω)) be n- dimensional Brownian motion and v = [vij (t, ω)] be a m × n That is: Brownian motion, the Stochastic integral Ito formula, the Girsanov theorem. Obviously we cannot go into the mathematical details. But the good news is, 1 Feb 2010 It includes the Lévy–Itô decomposition of a Lévy process and stochastic differential equations based on Lévy processes. In Section 2, we will Question: 4.

Lecture 18 : Itō Calculus f000(x) + 6: Now consider the term (B t)2. Since B tis a Brownian motion, we know that E[(B t) ] = 2 t. Since a di erence in B tis necessarily accompanied by a di erence in t, we see that the second term is no longer negligable.

### However, Ito integral is the most natural one in the context of how the time variable ts into the theory, because the fact that we cannot see the future is the basis of the whole theory. We will further study this in next section. 2. Properties of Ito calculus First theorem can be seen as an extension of the fact that the sum of

Two characteristics distinguish the Ito calculus from other approaches to integration, which may also apply to stochastic processes. Itō calculus, named after Kiyoshi Itō, extends the methods of calculus to stochastic processes such as Brownian motion (Wiener process).It has important applications in mathematical finance and stochastic differential equations.The central concept is the Itō stochastic integral.

The construction is based on a pathwise derivative, introduced by Dupire, for functionals on the space of right-continuous functions with left limits. We show that this functional derivative Itô calculus, named after Kiyoshi Itô, extends the methods of calculus to stochastic processes such as Brownian motion (see Wiener process).It has important applications in mathematical finance and stochastic differential equations.
