Convection in Navier-Stokes equations
Two funadamental approximations of the full set of the Navier-Stokes equations, i.e. for the mass conservation law, the momentum balance and the energy equation will be derived for convective systems. All the assumptios will be …

Pattern formation of a nonlocal, anisotropic interaction model
We consider a class of interacting particle models with anisotropic repulsive-attractive interaction forces whose orientations depend on an underlying tensor field. An example of this class of models is the so-called Kuecken-Champod model describing the …

Homogeneous functionals in the fair-competition regime
We study interacting particles behaving according to a reaction-diffusion equation with non-linear diffusion and non-local attractive interaction. This class of equations has a very nice gradient flow structure that allows us to make links to …

An Algorithm for Advancing Slow Features in Fast-Slow Systems without Scale Separation - A Young Measure Approach
In the first part of the talk, and in order to set the stage, we will offer a multi-scale and averaging strategy to compute the solution of a singularly perturbed system when the fast dynamics …

Emergence of large densities in chemotaxis-growth systems
We consider variants of the Keller-Segel system of chemotaxis which contain logistic-type source terms and therebyaccount for proliferation and death of cells. We briefly review results and open problems with regard to the fundamentalquestion whether …

Istnienie rozwiązań dla problemu najmniejszego gradientu
W problemie najmniejszego gradientu od dwudziestu lat znane są wyniki dotyczące istnienia i jednoznaczności rozwiązania w ściśle wypukłym obszarze dla ciągłych danych brzegowych. Okazuje się, że na płaszczyźnie możliwe jest pokazanie istnienia rozwiązania przy mniej …

Continuity of attractors for a non-autonomous singularly perturbed hyperbolic equation.
We study the non-autonomous dynamical system given by hyperbolic equation on a bounded domain $\Omega\subset\mathbb{R}^3$ $$ \epsilon u_{tt}+u_t-\Delta u=f_\epsilon(t,u). $$ This dynamical system has uniform, pullback, and cocycle attractors. For $\epsilon=0$ the limit parabolic equation …

On the steady flow of reactive gaseous mixture
I am going to talk about a system of equations describing stationary flow of chemically reactive gaseous mixture, which consist in stationary compressible Navier-Stokes-Fourier system coupled with equations describing evolution of fractional masses. I will …
