In the research we focus on the qualitative and numerical analysis of partial differential equations describing the derivative price changes of the underlying assets, such as interest rate derivatives or equities. We pay special attention to asymptotic and perturbation analysis of solutions depending on parameters and model calibrations for real market data. We also examine the problems leading to the solution of complementarity problems and variational inequalities appearing by valuation of American types of derivatives with early exercise.
