Adam Lipowski (Dept. of Physics, A.Mickiewicz University, Poznań)
On the ecological and evolutionary dynamics of prey-predator systems
I will discuss some aspects of the dynamics of interacting populations.In particular, I will talk about oscillatory behaviour and environmentally induced large-scale synchronization (Moran effect) in lattice models of prey-predator systems. More complicated models with …
March 8, 2007, 12:30 p.m.
Antoni Leon Dawidowicz (Institute of Mathematics, Jagiellonian University)
The Lasota equation and its properties

Daniel K. Wójcik (Instytut Biologii Doświadczalnej im. M. Nenckiego)
Introduction to nonequilibrium work relations
Nonequilibrium work relations discovered by Chris Jarzynski are an example of symmetries found recently for several classes of nonequilibrium problems. These symmetries typically connect probability of a given process with that of its "reverse". I …

Michalina Błażkiewicz
An attempt of mathematical description of kinematic parameters of hurdles, especially of the hurdle stride
The main objective of this presentation is utilization of mathematical apparatus for description of some kinematic parameters of hurdle race and analysis of position of limbs and of body centre of gravity during hurdle stride. …

Urszula Foryś (Uniwersytet Warszawski)
Generalization of the Greenspan MCS model to n-dimensional case
In tumour dynamics there is a well known model of spherical growth underthe diffusion of nutrient. The basic concept of multicellular spheroid (MCS) in 3-D was proposed by Greenspan. I'll show the formal generalization of …
Nov. 29, 2006, 4:15 p.m.
Tadeusz Płatkowski (Uniwersytet Warszawski)
Cooperation in Multiperson Prisoner's Dilemma Games - Social Loafing
Social loafing is the tendency for individuals to expend less effort when working collectively compared with when working individually. Such reduction of commonly appearing prosocial behavior was observed in the past by psychologists. Generally, the …
Nov. 22, 2006, 2:15 p.m.
Radosław Wieczorek (IMPAN Katowice)
From individual behavior of phytoplankton to evolution equation
Phytoplankton, a mass of small plants (mostly algae) living in the water, comes out to be the main source of nutrient in oceans. That is why understanding of its bahaviour becomes so important and has …

Ting Liu (Uniwersytet Warszawski)
Nonlinear impulse partial differential equations with delay

Urszula Foryś (Uniwersytet Warszawski)
Review on Delay Differential Equations, continuation but in fact the beginning
Oct. 18, 2006, 4:15 p.m.
Urszula Foryś (Uniwersytet Warszawski)
Review on Delay Differential Equations
We introduce the basic notation used in the theory of DDE, formulate the basic theorems and show some examples of the infuence of delays on the dynamics of the system.
May 24, 2006, 4:15 p.m.
Dorin Marinescu (Institute of Mathematical Statistics and Applied Mathematics, Romanian Academy, Bucharest)
Simulation methods for Boltzmann-type equations
We report on the numerical approximation of the solution of a general class of nonlinear Boltzmann like equations. We provide a discretized version of the equations approximating the above class of equations. The numerical implementation …
May 17, 2006, 4:15 p.m.
Krzysztof Argasiński (Uniwersytet Jagielloński)
Sex ratio evolution from the point of view of dynamic large games
On the seminar will be presented new model of sex ratio evolution related to so called dynamic evolutionary large games. This is a new technique of modelling of multipopulaton problems. The classic approach (e.g. Shaw-Moller …
April 5, 2006, 4:15 p.m.
Tomasz Lipniacki (IPPT)
Stochastic regulation of NF-kappaB pathway
Living cells may be considered noisy or stochastic biochemical reactors. In eukaryotic cells, in which the number of protein or mRNA molecules is relatively large, the stochastic effects may originate in regulation of gene activity …
March 28, 2006, 10:15 a.m.
Adam Bobrowski (IM PAN)
wspólne seminarium z RTN (On limitations and insufficiency of the Trotter-Kato theorem with applications to a model of stochastic gene expression II)
March 21, 2006, 10 a.m.
Adam Bobrowski (IM PAN)
On limitations and insufficiency of the Trotter-Kato theorem, with applications to a model of stochastic gene expression
Wspólne seminarium z RTN Modeling, Mathematical Methods and Computer Simulation of Tumour Growth and Therapy. Abstract: Motivation for the talk comes from a recent model of stochastic gene expression introduced by Lipniacki et al. (J. …
March 15, 2006, 4:15 p.m.
Jacek Miękisz (Uniwersytet Warszawski)
Stochastic models of genetic regulatory networks
Regulation of gene expression is a chemical process involving many coupled elementary chemical reactions modeled usually by systems of differential equations describing time evolution of molecular concentrations. However, due to low numbers of molecules involved …

Intermediate Modeling between Kinetic Equations and Hydrodynamic Limits: Application to the Spitzer-Harm regime
This work is devoted to the study of a problem resulting from plasma physics: heat transfer of electrons in a plasma close to Maxwellian equilibrium. A formal derivation from the Vlasov equations is proposed. A …

Model typu Fishera-Wrighta ze zmienna wielkoscia populacji i mutacjami w postaci procesu punktowego
Koalescencja Kingmana jest jednym z wazniejszych pojec genetyki populacyjnej. Jednak przybliza ona tylko proces dokadnej koalescencji (proces tworzenia drzew genealogicznych w modelu Fishera-Wrighta). Przedstawimy model populacji zbudowany w oparciu o proces dokladnej koalescencji z mutacjami …
