IFISC Seminar on Wednesday Jul 20, 2022 at 14:30 Place: IFISC Seminar Room Title: Type-I excitable media: a theoretical framework for space extended excitable systems Speaker: Pablo Moreno Spiegelberg, IFISC Abstract: <p>Excitability is a property of certain nonlinear dynamical systems concerning their response to external perturbations. Excitable systems can be classified into two classes, Type-I and II, with different dynamical properties and caused by different bifurcations. Excitable media, locally excitable spatial extended systems, show different regimes in which local perturbation exceeding a threshold can propagate across the medium. There are many studies considering Type-II excitable media, but much less is known about pulse propagation in the Type-I case. Recently, several vegetation systems compatible with Type-I excitability have shown traveling pulses, renewing interest in their study. In this seminar we will show the differences between both types of excitable media and characterize the properties of Type-I excitable pulses.</p> <p>Presential in seminar room, with parallel Zoom stream at&nbsp;https://zoom.us/j/98286706234?pwd=bm1JUFVYcTJkaVl1VU55L0FiWDRIUT09</p>; Url event:https://ifisc.uib-csic.es/en/events/seminars/type-i-excitable-media-a-theore...
