Summary | We aim to work on nonlinear generalization of the Black-Scholes equation for pricing financial instruments. The relevance of this subject relies on the fact that lhe classic Black-Scholes model has been established under some restrictive assumptions like e.g., frictionless, liquid and complete markets, etc. These assumptions do not hold in pratice which points out some drawbacks of the model. Addressing these issues leads us to the study of some mathematical problems that concern nonlinear PDEs or PIDEs. So, we will consider - nonlinear PDEs - nonlinear PIDEs - discretization and numerical analysis We will study the problem of existence of weak, or/ and viscosity solutions for parabolic PDEs and PIDEs related to the option pricing problem in financial models based on Gaussian or exponential Lévy processes, and the efficiency of numerical schemes for solving such PDEs and PIDEs. |
