Abstract: We consider a simplified model of an abstract object, formed by several narrow rectangles, which propels itself in a fishlike or rowing fashion in a fluid. The results include a formula for ``small'' motions of this model with the purpose to apply it to the study of
Il prossimo incontro di \Piz^2@TV(+IAC) si terrà il 7 maggio, sempre alle ore 13, presso il Dipartimento di Matematica di Roma Tor Vergata, aula "Dal Passo", sarà animato da Masayasu Mimura (Meiji Institute for Advanced Study of Mathematical Sciences, Meiji Univesrsity) e avrà come titolo: "Self-Organized Patterns in Bacterial Colonies".
Over the past ten years, our understanding of how spatio-temporal patterns in far from equilibrium systems has been rather deepened. Collaborative research of experimental and theoretical works have discovered the mechanism how complex patterns were generated in biological systems. It is emphasized that genetics does not always reveal the occurrence of such patterns and even simple systems may generate regular as well as chaotic irregular patterns in a self-organized way. Budrene and Berg observed diverse complex colonial patterns of chemotactic bacteria of E.coli ([1],[2]) (the following is one of the patterns). The aim of this talk is to support that such patterns are generated in a self-organized way by using modeling approach.
Keywords: colonial pattern formation, chemotactic mobility, self-organization.
