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.

A minimal protein-like lattice model
I will summarize results of my papers with Andrzej Kolinski. We have designed a minimal model of protein folding that reproduces in a qualitative way the most pronounced features of globular proteins. Using Monte Carlo …

Michał Matuszak (UMK)
Smooth Conditional Trajectory Evaluation in Dynamical Gaussian Networks
The seminar will present possibilities of applying Gaussian networks in realistic animation of virtual characters and optimal redeployment in multiagent environments. It will be achieved by solving the variational equations for Freidlin-Wentzell action functionals.

Symmetries and exact solutions of the diffusive Lotka-Volterra system
Lie and conditional symmetries of the classical Lotka-Volterra sys- tem inthe case of one space variable are completely described and sets of suchsymmetries in explicit form are constructed. These symmetries are used toreduce the classical …

Boundary stabilization of a 3-D Navier Stokes flow in the neighborhood of an unstable equilibrium
Połączone seminarium: Równania Fizyki Matematycznej i Biomatematyka i Teoria GierWe shall consider a 3-D Navier Stokes flow defined in the neighborhood of an unstable equilibrium. For large Reynolds numbers, the steady state solutions are unstable …

Family of angiogenesis models with discrete delays
We will discuss a family of models with delays describing the process of angiogenesis, that is a physiological process involving the growth of new blood vessels from pre-existing ones. This family includes the well known …

O własnościach gatunków semelpatrycznych
Gatunek semelpatryczny, to taki, którego przedstawiciele rozmnażają się raz w życiu i umierają. Będziemy dodatkowo zakładać, że długość życia osobników n jest stała. Przedstawimy model struktury-wiekowej populacji semelpatrycznej z dyskretnym czasem. Dla n=1 model redukuje …
