This course employs an incremental approach to build on existing knowledge of Partial Differential Equations (PDE) and numerical methods. The structure includes five blocks covering the basics of PDE, finite difference methods (FDM) for one-factor and two-factor Black-Scholes models, and advanced issues such as approximating Greeks and parabolic variational inequalities. Students will learn algorithm implementation, performance evaluation, and integration with Excel, culminating in a deep understanding of both theoretical and practical aspects of numerical solutions in financial engineering.
