From diffusions on graphs to Markov chains via asymptotic state lumping
We show that finite-state Markov chains may be approximated by fastdiffusions on finite graphs with semi-permeable membranes on vertices.The approximation involves a singular perturbation with singularity inboth operator and boundary/transmission conditions. The result ismotivated by …

Game dynamics for players with complex personalities
We consider populations of individuals who are engaged in n--person publicgood games or in two--person non symmetric or symmetric social dilemmagames. The players imitate the most attractive strategies, and the choiceis motivated not only by …

More on linear differential systems with small delays
We'll study the aysymptotic dynamics of linear systems of DDEs with small delays. It can be shown that asymptotically such systems behave as the so-called special solutions and for linear DDEs these solutions coincide with …

Hipoteza Zielonej Ziemi - model komputerowy
Wszechobecność roślin zielonych zainspirowała Hairstona, Smitha i Slobodkina do opracowania ogólnej teorii kontroli populacji lądowych. W Hipotezie Zielonej Ziemi (HSS) zauważyli oni, że do znacznego uszczuplenia populacji roślin dochodzi niezmiernie rzadko, liczebność (biomasa) roślinożerców zatem …

Natalia Bielczyk (Uniwersytet Warszawski)
Dynamical Models of Dyadic Interactions with Time Delay
We will discuss a general class of linear models of dyadic interactions with a constant discrete time delay. In such models, changes of stability of stationary points occur for various intervals of parameters which determine …

Michał Matuszak (UMK Toruń)
Coevolution of networks and strategies
Evolution of cooperation, within a framework of Prisoner's Dilemma game, on scale-free graphs will be discussed. We will present coevolutionary stochastic dynamics which lead to scale-free graphs with various exponents.

Equations with small delays
I'll present a review of known results concerning equations with small delays. This talk will be mainly focused on linear and semi-linear delay differential equations with small delays.
