Effects of time delay on stability for simple linear DDEs
We illustrate the influence of time delay on the stability of steady state for some simple linear delay differential equations. We prove that for one DDE with one discrete delay the only stability switch that …

Monika Piotrowska (Uniwersytet Warszawski)
O pracy Tembine, Altmana i El-Azouzi czyli o symetrycznych i asymetrycznych opóźnieniach w grach ewolucyjnych.
Zajmiemy się tematyką opóźnień w symetrycznych grach ewolucyjnych, gdzie z każdą czystą strategią powiązane jest dyskretne opóźnienie pojawiające się w równaniach replikatorowych.

Daniel Wójcik (Nencki Institute of Experimental Biology)
Simple point process models of neural spike trains
A necessary ingredient for a quantitative theory of neural coding is appropriate spike kinematics: a precise description of spike trains - sequences of standard voltage impulses used for communication between neurons. While summarizing experiments by …

Marek Bodnar (Uniwersytet Warszawski)
Stability of the expected value and boundness of the variance of some stochastic time-delay differential equation and its application to the hemapoietic stem cell regulation system
The results of work of J. Lei and M. Mackey (SIAM J. Appl. Math., 67, 387-407 (2007)) will be presented. We will study the stability of the trivial solution of a stochastic delay differential equation …

Denaturacja DNA i pewne równania różniczkowo-całkowe
Zostanie przedstawiona pewna klasa równań różniczkowo-całkowych i dość desperacka próba opisu zjawiska denaturacji DNA (pękania wiązań wodorowych)pod wpływem temperatury - tzw. topnienie DNA.

Ofer Biham (Racah Insitute of Physics, The Hebrew University, Jerusalem)
Stochastic analysis of toggle switch and toxin-antitoxin modules
Regulation processes in cells are performed by networks of interacting genes, which regulate each other's expression. To analyze the function of genetic networks, we simulate the dynamics of small functional modules using stochastic methods which …

Jan Poleszczuk (Uniwersytet Warszawski)
Validity of delayed differential equations in biochemical reactions systems
It is well known that the time evolution of spatially homogeneous mixture composition consisting of molecules from N different species that can react through M chemical channels can be deterministically described by some set of …

Agnieszka Wiszniewska-Matyszkiel (Uniwersytet Warszawski)
Evolutionary games with continuous strategy spaces
We shall consider evolutionary games based on games with continuous strategy spaces. Properties of replicator and adaptive dynamics will be described. The sequence of presentations will be based on papers of Oechsler & Riedel, Cressman, …

Stochastic fluctuations in selection model based on evolutionary game theory
April 22, 2009, 4:15 p.m.
Jan Zakrzewski (Uniwersytet Warszawski)
Stochastic fluctuations in selection model based on evolutionary game theory
We will investigate frequency-dependent selection model (with one locus, two alleles, two phenotypes and finite population) based on evolutionary game theory. Next we will include stochastic fluctuations in the model, and convert deterministic equation into …
