Heston models are bivariate composite models. Each Heston model consists of two coupled univariate models: A geometric Brownian motion ( gbm) model with a stochastic volatility function. This model usually corresponds to a price process whose volatility (variance rate) is governed by the second univariate model.

In the derivation of S. L. Heston's model [23], Îto's formula yields the following diffusion equation. (1.2).

The Heston model was introduced by Steven Heston’s A closed-form solution for options with stochastic volatility with applications to bonds an currency options, 1993. For a fixed risk-free interest rate , it’s described as:
