Double phase functionals and approximation
The talk shall introduce double-phase functionals and spaces, and discuss their approximation properties. The spaces of our interest are inhomogeneous Sobolev-type spaces, which lie between classical Sobolev spaces. We shall see that regular functions are …

Effective nonlinear models in many body problems.
We shall discuss how nonlinear models arise as effective theories in many body physics, with main focus on nonlinear Schrödinger-type equations. In particular, we will cover new applications in the theory of ions immersed in …

A mixed-dispersion equation in dimension 4: results and open problems
I will present results concerning the existence of unbounded sequences of solutions, obtained via variational methods, to an elliptic mixed-dispersion equation in dimension 4, in the so-called positive-mass and zero-mass cases. Specific symmetries are used …

A fluid-particle interaction model
In 2011 three authors J.A. Carrillo, T. Karper and K. Travisa published the paper "On the dynamics of a fluid-particle interaction model: The bubbling regime". They discussed a model, where particles of one fluid are …

Filamentary structure of streamers in Transient Luminous Events
The subject of the seminar will be a numerical modelling of instabilities in a weakly-ionized plasma with a use of kinetic theory plasma models. The natural phenomenon being treated is the process of branching (filamentation) …

Discretization of Wasserstein Gradient Flow
We consider the local model and the model with non-local interactions with linear diffusion as equivalent problems to the gradient flow along a convex functional. In the first part, the local model is considered. We …

Energy quantization of Willmore surfaces with bounded index
Quantization phenomena, pioneered by Sacks-Uhlenbeck in 1981, arise in the study of compactness questions of every conformally invariant functional and requires a subtle analysis. In the context of Willmore surfaces, the first study of such …

Strong density in Sobolev spaces to manifolds
In striking contrast with what happens to classical Sobolev spaces, the space of smooth maps with values into a compact manifold $N$ does not need to be dense in the space of $N$-valued $W^{s,p}$ maps. …
