Analytical Study of a Triple Hopf Bifurcation in a Tritrophic Food Chain Model
J. -P. Francoise, J. Llibre
We provide an analytical proof of the existence of a stable periodic orbit contained in the region of coexistence of the three species of a tritrophic chain. The method used consis…
Exact boundary observability for nonautonomous quasilinear wave equations
Lina Guo, Zhiqiang Wang
By means of a direct and constructive method based on the theory of semiglobal solution, the local exact boundary observability is shown for nonautonomous 1-D quasilinear wav…
Tackling the Gross-Pitaevskii energy functional with the Sobolev gradient - Analytical and numerical results
P. Kazemi, M. Eckart
In the first part of this contribution we prove the global existence and uniqueness of a trajectory that globally converges to the minimizer of the Gross-Pitaevskii energy function…
Oscillations and Random Perturbations of a FitzHugh-Nagumo System
Catherine Doss, Michèle Thieullen
We consider a stochastic perturbation of a FitzHugh-Nagumo system. We show that it is possible to generate oscillations for values of parameters which do not allow oscillations for…
Loss of smoothness and energy conserving rough weak solutions for the 3d Euler equations
Claude Bardos, Edriss S. Titi
A basic example of shear flow was introduced by DiPerna and Majda to study the weak limit of oscillatory solutions of the Euler equations of incompressible ideal fluids. In particu…
Functions with Prescribed Best Linear Approximations
P. L. Combettes, N. N. Reyes
A common problem in applied mathematics is to find a function in a Hilbert space with prescribed best approximations from a finite number of closed vector subspaces. In the present…
