In probability theory, a McKean–Vlasov process is a stochastic process described by a stochastic differential equation where the coefficients of the diffusion depend on the distribution of the solution itself. [1] [2] The equations are a model for Vlasov equation and were first studied by Henry McKean in 1966. [3]
A stochastic differential equation (SDE) is a differential equation in which one or more of the terms is a stochastic process, [1] resulting in a solution which is also a stochastic process. SDEs have many applications throughout pure mathematics and are used to model various behaviours of stochastic models such as stock prices , [ 2 ] random ...

In finance, the Heston model, named after Steven L. Heston, is a mathematical model that describes the evolution of the volatility of an underlying asset. [1] It is a stochastic volatility model: such a model assumes that the volatility of the asset is not constant, nor even deterministic, but follows a random process.
By Jill Krasny and Zachry Floro Math class may have seemed pointless back in the day, but it turns out all those confusing equations are quite useful. Math can be used to solve every money problem ...
Basic tools of econophysics are probabilistic and statistical methods often taken from statistical physics.. Physics models that have been applied in economics include the kinetic theory of gas (called the kinetic exchange models of markets [7]), percolation models, chaotic models developed to study cardiac arrest, and models with self-organizing criticality as well as other models developed ...
An important application of stochastic calculus is in mathematical finance, in which asset prices are often assumed to follow stochastic differential equations.For example, the Black–Scholes model prices options as if they follow a geometric Brownian motion, illustrating the opportunities and risks from applying stochastic calculus.
The solution of the PDE gives the value of the option at any earlier time, [{,}]. To solve the PDE we recognize that it is a Cauchy–Euler equation which can be transformed into a diffusion equation by introducing the change-of-variable transformation
