Masahiko Ando M.D.,Atsuyoshi Takao M.D.ed as a function of at least one additional stochastic process. Such models can explain some of the empirical properties of asset returns, such as volatility clustering and the leverage effect. These models can also account for long term smiles and skews.

Succinctness for Singleton Setsts. The dependence structure of the Brownian motion part of the Lévy process is given by its covariance matrix. For purposes of financial modeling, it remains to specify a parametric dependence structure of the purely discontinuous part which can be done by using Lévy copulas.

Elements of Numerical Methods for PDEsare mostly parabolic. Occasionally, however, elliptic PDEs arise in connection with so-called “infinite horizon problems”, and hyperbolic PDEs may appear in certain pure jump models with dominating drift.

Finite Element Methods for Parabolic Problemse.g. for binary contracts. The basis for finite element discretization of the pricing PDE is a variational formulation of the equation. Therefore, we introduce the Sobolev spaces needed in the variational formulation and give an abstract setting for the parabolic PDEs.

Elements of Numerical Methods for PDEsolic and hyperbolic equations, and we indicate the corresponding type of problems that they model. PDEs arising in option pricing problems in finance are mostly parabolic.

Finite Element Methods for Parabolic Problemsnts is that they give convergent deterministic approximations of option prices under realistic, low smoothness assumptions on the payoff function as, e.g. for binary contracts. The basis for finite element discretization of the pricing PDE is a variational formulation of the equation. Therefore, we
