Analysis of Geophyscial Flows
The primitive equations of geophysical fluid dynamics are regarded as a
standard model for oceanic and atmospheric dynamics and are derived from the Navier-Stokes equations by assuming a hydrostatic balance for the pressure term. They have been introduced by Lions, Temam and Wang in the 90s. Since then the incompressible and compressible primitive equations have been to subject of intensive mathematical investigations.
In this talk we discuss and investigate classical as well as recent developments in this direction. In particular, we investigate global, strong well-posedness results for an atmosphere-ocean system coupled by fully nonlinear conditions at the interface, the effects of stochastic winddriven boundary conditions and transport noise as well as an energy balance model subject to dynamic boundary conditions with and without noise on the boundary.
This is joint work with A. Agresti, T. Binz, F. Brandt, A. Hussein and T.
Zochling.

Exponential stability of a nonlocal micro-beam system
This work is concerned with the exponential stability of a nonlocal micro-beam system. In order to handle the problem, the minimal state approach is adopted. This allows us to show, on one hand, that the problem is well-posed in the sense of semigroups theory. On the other hand, the exponential stability of the solutions is established by means of the energy method. These outcomes extend the previous ones where the impact of memory phenomenon is disregarded.
