Clarification and complement to "Mean-field description and propagation of chaos in networks of Hodgkin-Huxley and FitzHugh-Nagumo neurons" [PDF]

open access: yes, 2015
In this note, we clarify the well-posedness of the limit equations to the mean-field $N$-neuron models proposed in Baladron et al. and we prove the associated propagation of chaos property. We also complete the modeling issue in Baladron et al.

Nagumo conditions and second-order quasilinear equations with compatible nonlinear functional boundary conditions

open access: yesRocky Mountain Journal of Mathematics, 2011
Assuming the existence of ordered lower and upper solutions for \[ -\frac{d}{dt} \varphi(t,x,x(t),x'(t))=f(t,x,x(t),x'(t)) \quad \text{a.e. on } [0,1], \] the authors establish the existence of solutions to the above differential equation subject to general functional boundary conditions of the form \[ G(x(0),x(1),x,x'(0),x'(1))=(0,0), \] where ...

Semigroups generated by pseudo-contractive mappings under the Nagumo condition

open access: yesJournal of Differential Equations, 2008
This paper gives important results on existence on closed sets of a differential equation of type \(u'=Tu-u\) in Banach spaces. A weak tangency condition of Nagumo type is imposed. The operator \(T\) is demicontinuous and pseudo-contractive. Local as well as global solutions are investigated. Fixed points results are given as applications.

Upper and lower solutions for BVPs on the half-line with variable coefficient and derivative depending nonlinearity

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
This paper is concerned with a second-order nonlinear boundary value problem with a derivative depending nonlinearity and posed on the positive half-line. The derivative operator is time dependent.

Positive solutions for boundary value problems of a class of second-order differential equation system

open access: yesOpen Mathematics, 2023
This article discusses the existence of positive solutions for the system of second-order ordinary differential equation boundary value problems −u″(t)=f(t,u(t),v(t),u′(t)),t∈[0,1],−v″(t)=g(t,u(t),v(t),v′(t)),t∈[0,1],u(0)=u(1)=0,v(0)=v(1)=0,\left\{\begin{

Synchronization of Traveling Waves in Memristively Coupled Ensembles of FitzHugh–Nagumo Neurons With Periodic Boundary Conditions

open access: yesFrontiers in Physics, 2022
Synchronization of traveling waves in two rings of FitzHugh–Nagumo neurons is studied. Coupling between neurons within each ring is dissipative, while one between rings is memristive. Complete synchronization of waves in identical rings in the presence of an initial phase shift between wave processes and partial synchronization of waves in the case of ...
