The Evaluation of American Option Prices Under Stochastic Volatility and Jump-Diffusion Dynamics Using the Method of Lines [PDF]
This paper considers the problem of numerically evaluating American option prices when the dynamics of the underlying are driven by both stochastic volatility following the square root process of Heston (1993), and by a Poisson jump process of the type ...

High Order Finite Element Solution of Elastohydrodynamic Lubrication Problems [PDF]
In this thesis, a high-order finite element scheme, based upon the Discontinuous Galerkin (DG) method, is introduced to solve one- and two-dimensional Elastohydrodynamic Lubrication (EHL) problems (line contact and point contact). This thesis provides an

A p-cycle analysis of multigrid method
We suggest a new strategy for multigrid iterations based on our analysis for p-cycle multigrid method. First, we improve a recent result on multigrid V-cycle analysis given by Bramble and Pasciak to p-cycle multigrid method.

Numerical radiative transfer using a multigrid method
Solving the non-LTE radiative transfer problem in stellar atmospheres is computationally demanding. There is therefore an interest to investigate new methods to solve this problem effectively.
