The goal of this book is to develop robust, accurate and efficient numerical methods to price a number of derivative products in quantitative focus on one-factor and multi-factor models for a wide range of derivative products such as options, fixed income products, interest rate products and ‘real’ options. Due to the complexity of these products it is very difficult to find exact or closed solutions for the pricing functions. Even if a closed solution can be found it may be very difficult to compute. For this and other reasons we need to resort to approximate methods. Our interest in this book lies in the application. | difference methods in financial engineering A Partial Differential Equation Approach Finite Difference Methods in Financial Engineering A Partial Differential Equation Approach Daniel J.
