Friction dominated dynamics of interacting particles locally close to a crystallographic lattice. Self-contained continuation

Karol Wawrzyniak (ICM UW & National Centre for Nuclear Research)
On Phenomenology, Dynamics and some Applications of the Minority Game
Minority game (MG) was designed as a microscopic model of adaptive behavior observed in multi-agent systems where being in minority is profitable. It was shown that the MG exhibits different modes of behavior, depending on …

Marek Bodnar (Uniwersytet Warszawski)
Friction dominated dynamics of interacting particles locally close to a crystallographic lattice
We study a system of particles, in general d-dimensional space, that interact by means of pair potential and adjust their positions according to the gradient flow dynamics induced by the total energy of the system. …

Roman Cherniha, (Institute of Mathematics of NASU, National University 'Kyiv-Mohyla Academy ')
Mathematical model for fluid-glucose-albumin transport in dialysis and its steady-state solutions
Mathematical description of fluid and solute transport between blood anddialysis fluid in the peritoneal cavity has not been formulated fully yet,in spite of the well known basic physical laws for such transport. Recentmathematical, theoretical and …

Maria Vela-Perez (IE University, Segovia)
Geodesic paths in simple graphs for some social insects
Social insects are an important example of complex collective behavior.In particular, ant colonies develop diff erent tasks as foraging, buildingand allocation [1]. While they search for food they deposit a pheromonethat it is considered as …

Tatiana Ryabukha (Institute of Mathematics, National Academy of Sciences of Ukraine and MIMUW)
Non-equilibrium cluster expansions in the theory of many-particle dynamical systems
This talk deals with analytical methods in statistical mechanics. It'sgoal is to give a deductive presentation of the statistical mechanics ofnonequilibrium systems based on BBGKY hierarchy studying - description ofthe evolution of states - as …
May 25, 2011, 4:15 p.m.
Adam Bobrowski (Politechnika Lubelska)
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 …

Tadeusz Płatkowski (Uniwersytet Warszawski)
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 …
