Tomasz Piasecki (Uniwersytet Warszawski (MIM))
On the stationary flow of a reactive gaseous mixture
We are interested in a system of equations describing stationary flow of a mixture of gases undergoing reversible chemical reactions. The system consists of the stationary compressible Navier-Stokes-Fourier equations coupled with reaction-diffusion equations describing balance …

Tokinaga Namba (University of Tokyo)
Well-posedness of Hamilton-Jacobi equations with Caputo’s time-fractional derivative
For the diffusion phenomena of substances in the domain with a fractal structure, it has been confirmed through experiments that it is better to consider diffusion equations replaced the integer order time derivatives with Caputo’s …
May 11, 2017, 12:30 p.m.
Mahdi Boukrouche (Jean Monnet University)
3D unsteady Navier-Stokes problem with memory and subdifferential boundary condition
We consider a mathematical model which describes the motion of a 3D unsteady fluid flow governed by Navier-Stokes system, and subjected to mixed boundary conditions with a given velocity on one part of the boundary …

Jakub Siemianowski (Uniwersytet Mikołaja Kopernika w Toruniu)
The global attractor for weak and strong solutions of 2D thermomicropolar fluid flow
We present the notion of the weak and strong solutions of 2D thermomicropolar fluid equations. We show that there is a problem in showing the uniqueness of weak solutions. Nevertheless, we will examine the multivalued …
April 27, 2017, 12:30 p.m.
Krzysztof Mizerski (Instytut Geofizyki PAN)
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 …
March 30, 2017, 12:30 p.m.
Lisa Maria Kreusser (University of Cambridge)
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 …
March 23, 2017, 12:30 p.m.
Franca Hoffmann (University of Cambridge)
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 …
March 9, 2017, 12:30 p.m.
Edriss S. Titi (Texas A&M University and The Weizmann Institute of Science)
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 …

Martin Michalek (Charles University)
Compressible fluids, models and weak solutions

Piotr Rybka (Uniwersytet Warszawski (MIM))
Dynamic boundary conditions for the total variation flow
Dec. 8, 2016, 11 a.m.
Prof. Michael Winkler (Universitat Paderborn)
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 …
