We now enter the part of the book that is devoted to the numerical solution of equations of the Black-Scholes type. Here we discuss “standard” options in the sense as introduced in Section 1.1. Accordingly, let us assume the scenario characterized by the Assumptions 1.2. In case of European options the function

Ultimately it is our intention to solve more general equations and inequalities. In particular, American options will be calculated numerically. The goal is not only to calculate single values
