Nov. 20, 2019, noon
Iwona Chlebicka (MIM UW)
PDEs in inhomogeneous and anisotropic spaces with general data
I would like to present an introduction to equations describing diffusion-type processes in media of complicated structure. This type of problems require to employ unconventional functions spaces. I will try to give some intuition by …

Agnieszka Wiszniewska-Matyszkiel / Mirosław Lachowicz (MIM UW / MIM UW)
"The tragedy of the commons" in various aspects and theory of dynamic games and dynamic optimization / Opinion dynamics: "E pur si spera"?
Oct. 30, 2019, 12:15 p.m.
Aleksadra Puchalska / Miroslaw Lachowicz (MIM UW / MIM UW )
'Impact of exchange in nodes' mechanisms on the asymptotic properties of network transport model / Opinion dynamics: 'E pur si spera'?'
A. Puchalska (MIM UW), Mixed PDE-ODE network problem with McKendrick boundary condition; Abstract: In the talk we present a new network model with dynamics described by transport equation on edges and ODEs in vertices. Transfer …
Oct. 23, 2019, 12:15 p.m.
Dominika Jasińska / Jurij Kozicki (Maria Curie-Sklodowska University, Lublin)
Dynamics of infinite age-structured populations / A Markov process for an infinite interacting particle system in the continuum
(1) Dominika Jasińska (Maria Curie-Sklodowska University, Lublin, and MIM UW, Poland) "Dynamics of infinite age-structured populations": Abstract: A Markov evolution of an infinite age-structured population of migrants is studied. Its members are point entities characterized …

Raffi Vardanyan ((doktorant MIM) )
Three-player games with strategy-dependent time delays
In this presentation the results of the cooperative project with Jacek Miekisz and Marek Bodnar about replicator dynamics with strategy-dependent time delays in three-player games are presented. Certain parameters are considered providing one pure and …
May 29, 2019, 2:15 p.m.
Fayz Ali Al-hag (doktorant MIM)
Sustainability of social optima and Nash equilibria in a differential game of resource extraction
In this presentation we study a game related to a model of sustainability of social optima and Nash equilibria in a differential game of resource extraction in infinite time horizon. We study the social optimum …
April 24, 2019, 2:15 p.m.
Adam Prosiński (Oxford University)
Calculus of variations in the anisotropic setting
In this talk, we will review some recent results concerning existence and regularity of minimizers of anisotropic variational problems. The anisotropy that we have in mind concerns different orders of derivation in different directions, thus …
April 17, 2019, 2:15 p.m.
Dominika Machowska (Uniwersytet Łódzki)
Delayed and cumulative effects of advertising in a cooperative or competitive environment
In this talk, I investigate the goodwill dynamics evolved à la Nerlove–Arrow in which delayed or cumulative effects of advertising is included. As a result, a cooperative differential game is formulated for which I investigate …
March 27, 2019, 2:15 p.m.
Marcin Choiński (Uniwersytet Warszawski (MIM))
Flip bifurcation in discrete models
I will talk about flip bifurcation, which can occur in discrete models. Firstly, I will define what the flip bifurcation is, then I will analyze this kind of bifurcation in Ricker's population equation. The presentation …
March 13, 2019, 2:15 p.m.
Urszula Foryś (Uniwersytet Warszawski (MIM))
More about Lyapunov function for simple epidemic models
During my previous presentation I have shown some examples of Lyapunov functions for simple epidemic model with constant influx to the susceptible population. However, presented functions do not work for no influx. I would like …
March 6, 2019, 2:15 p.m.
Piotr Bajger (doktorant MISDoMP)
Effects of Pharmacokinetics and DNA Repair on the Structure of Optimal Controls in a Simple Model of Radio-chemotherapy
In this talk two models of radiochemotherapy are considered. A reference simple model adopts a classical log-kill hypothesis for chemotherapy and a linear-quadratic response for radiotherapy. The model is represented by first order nonlinear differential …
Feb. 28, 2019, 12:30 p.m.
Natalia Bielczyk (PhD candidate Stichting Solaris Onderzoek en Ontwikkeling, Nijmegen, the Netherlands)
On applied mathematics in brain research & on the open project entitled 'Effective Self-Management for Early Career Researchers in the Natural Sciences
In this seminar, I will review two topics. Firstly, I will briefly review my PhD research within the Donders Graduate School, Donders Institute for Brain, Cognition and Behavior, Nijmegen, the Netherlands. My work concerns developing …
