Giant planet interiors in the light of the Juno and Cassini missions
The Juno mission to the planet Jupiter has revealed significant new information about the processes going on inside the planet. Similar data for Saturn was obtained from the Cassini grand finale. Accurate measurements of Jupiter’s …

Parabolic-elliptic and parabolic systems in diffusion models
The presentation deals with nonlinear parabolic--elliptic and parabolic systems with initial-boundary conditions modeling biological ion channels and interdiffusion in solids. I will formulate theorems on local and global existence, uniqueness and properties of weak solutions, …

Existence of weak solutions to compressible Stokes system with general pressure
In the presentation I will talk about the existence and uniqueness of weak solutions to the compressible Stokes system. Using the Lagrangian formulation, we are able to prove that the solution is globally bounded, provided …

Metoda FMD (projektowanie materiałów z wolnego wyboru)
The presentation deals with minimization of the weighted average of compliances of structures, made of an elastic material of spatially varying elasticity moduli, subjected to n load variants acting non-simultaneously. The trace of the Hooke …

Time Reversal - an efficient way of data analysis
Building knowledge on surrounding world requires information about it. This almost trivial statement gains a much deeper sense in cases when we cannot infer thought information by direct measurements. It happens quite often, actually too …

Applications of PDEs in functional spaces with a measure or a weight
In my presentation I want to discuss two problems to which applying methods of PDEs in functional spaces that depend on a certain kind of measure seems to be fruitful. Describing a process of transfer …

Applications of mathematics in astrophysical hydrodynamics
The aim of the seminar is to present approaches and problems that arise in the analysis of dynamics of planetary and stellar fluid interiors. This involves the convective heat transfer in the presence of density …

Pandemia COVID19 oczyma ignoranta
Chciałbym zrobić heurystyczne wprowadzenie do modelowania pandemii COVID19, która nas dotknęła w tym roku. Głównym elementem będą modele typu SEIR, opisujące uśrednioną populację. Wydawałoby się, że predykcje dynamiki takiej pandemii są bardzo ważne, ale ... …

Układy dynamiczne jako narzędzie do modelowania procesów związanych ze świadomością
Teoria Zintegrowanej Informacji to zaproponowany przez Giulio Tononiego formalizm stosowany do opisu zjawisk związanych ze świadomością. Przedstawię założenia tej teorii oraz omówię oparte o nią modele wykorzystujące układy dynamiczne i ich atraktory. ------------------------------------------------------------------------------ Join …

Turbulent clustering of low-inertia droplets
Several effects of turbulence may reduce the time for rain initiation in warm (ice-free) atmospheric clouds. This talk overviews the effect of turbulent clustering of inertial droplets that interact hydrodynamically. Using the so-called drift-diffusion model (based on the Master …

Adjoint-Based Optimal Control of Incompressible Flows with Energy-Stable Boundary Conditions
Problems arising in computational fluid dynamics often require artificially truncating the domain and posing appropriate open boundary conditions. However, these are known to suffer from backflow instability – when the flow at the boundary reverses, …
