The Black-Scholes Equation
Model ID: 82
The Black-Scholes equation, computes the value u of a European stock option. Black-Scholes derived an analytical expression for the solution to this problem. However, the formula works only for certain cases; for instance, you cannot employ it when sigma and r are functions of x and t. Here, sigma denotes the volatility, r the continuous compounding rate of interest, and x the underlying asset price.
Using a PDE formulation allows you to determine the price for such cases. This model sets up the PDE formulation of the Black Scholes equation and in addition, this model also shows how to solve the 1D time-dependent variation using a 2D geometry with the y-coordinate corresponding to time.
