The cosmological predictions of the angular power spectrum and structure formation are dependent on the chosen initial conditions of perturbations at early radiation dominated epoch. I will start by introducing the general mathematically possible initial conditions for scalar perturbations. Single field inflationary models produce Adiabatic initial conditions and the current CMB data strongly supports adiabatic initial conditions. With multi-field inflationary models one can produce isocurvature perturbations. A signal for isocurvature perturbations is of high importance for particle physicists as they predict the existence of exotic particles like axions and curvatons. I would present my work on trying to find an evidence for a (possibly) correlated adiabatic and isocurvature mode. The CMB datasets used for constraining models are WMAP9, QUaD and ACBAR. In the end, I would discuss the current status of isocurvature perturbations after PLANCK.

Finite volume methods for elasticity and poro-elasticity
Abstract: We introduce a new class of cell-centered finite volume methods for elasticity and poro-elasticity. This class of discretization methods has the advantage that the mechanical discretization is fully compatible (in terms of grid and variables) to the standard cell-centered finite volume discretizations that are prevailing for commercial simulation of multi-phase flows in porous media.
For a specific variant of the proposed discretization, we give an overview of a convergence proof in the setting of isotropic elasticity, and address from a theoretical perspective the issues of a discrete Korn's inequality and robustness with respect to locking. Furthermore, we give numerical results for both structured and unstructured grids for both elasticity and poro-elasticity. The talk concludes with an application to simulation of fractured and fracturing porous media.
Risk measures are set to quantify in terms of assets/money the amount of financial risk associated to a certain financial position. The purposes for such evaluations are many and interesting both from the investors perspectives and regulators. As example, these evaluations are important to quantify the amount of reserve that financial institutions, such as banks or insurance companies, have to set aside as hedging guarantee. In the recent years large attention is given towards convex and coherent risk measures.
A series of 10 lectures will be held by Prof. Giacomo Scandolo, Department of Mathematics, University of Verona (Italy), visiting scholar at our department.
The course is suggested to Master and PhD students in the area of Stochastic Analysis, Insurance, and Risk as well as practitioners in the area.
