16. On Lévy Processes in Mathematical Finance
Abstract : The focus of the first article, On the Modelling of Financial Data with Generalized Hyperbolic Distributions, lies in studying the performance of the generalized hyperbolic distribution (GH), when fitted to historical data. Four different areas were selected. READ MORE

17. Finite element approximation of the linear stochastic Cahn-Hilliard equation
Abstract : The linearized Cahn-Hilliard-Cook equation is discretized in the spatial variables by a standard finite element method. Strong convergence estimates are proved under suitable assumptions on the covariance operator of the Wiener process, which is driving the equation. The backward Euler time stepping is also studied.

18. Bayesian learning of structured dynamical systems
Abstract : In this thesis, we propose some Bayesian approaches to the identificationof structured dynamical systems. In particular, we consider block-orientedmodels in which a complex system is built starting from simple linear andnonlinear building blocks. READ MORE

19. Two-Barrier Problems in Applied Probability: Algorithms and Analysis
Abstract : This thesis consists of five papers (A-E). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x0. We define the loss rate due to the reflection. READ MORE

20. Essays in mathematical finance : modeling the futures price
Abstract : This thesis consists of four papers dealing with the futures price process. In the first paper, we propose a two-factor futures volatility model designed for the US natural gas market, but applicable to any futures market where volatility decreases with maturity and varies with the seasons.
