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 two mixed Nash equilibria in biological type mod...

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 and Nash equilibrium problems. ...

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 we work with differential operators that need not be hom...

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 the optimal solution and analyse some properties of it. In t...

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 will be based on Kuznetsov's book „Elements of Applied Bifurca...

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 to present how the method of separated variables could be used for propo...

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 equations with two control variables which ca...
