Witryna3 gru 2009 · In the last part of this chapter, we study third order systems when the right member f sa- tisfies a Wintner-Nagumo growth condition. To obtain an existence result in this case, we use the theory of differential inclusions. This result generalizes in many ways a theorem due to Grossinho and Minhós [34]. Witryna31 maj 2012 · We derive the mean-field equations arising as the limit of a network of interacting spiking neurons, as the number of neurons goes to infinity. The neurons belong to a fixed number of populations and are represented either by the Hodgkin-Huxley model or by one of its simplified version, the FitzHugh-Nagumo model.

Dans le cadre des équations différentielles, le critère de Nagumo est un critère suffisant d'unicité locale d'une solution à un problème de Cauchy. Joint au théorème d'existence locale de Cauchy-Peano-Arzelà, il assure donc la même conclusion que le théorème de Cauchy-Lipschitz, sous des hypothèses différentes. http://www.tommsch.com/misc/remarks_nagumo.pdf gravity falls candy voice actor
