Global Bifurcation for the Whitham Equation [PDF]
Mathematical Modelling of Natural Phenomena, 2013 We prove the existence of a global bifurcation branch of $2π$-periodic, smooth, traveling-wave solutions of the Whitham equation. It is shown that any subset of solutions in the global branch contains a sequence which converges uniformly to some solution of Hölder class $C^α$, $α< \frac{1}{2}$.

Hopf Bifurcation and Global Dynamics Analysis of Generalized Sprott L System
Zanco Journal of Pure and Applied Sciences, 2023 A simple chaotic system with only one nonlinearity and five terms was introduced by Sprott. We consider the generalized Sprott differential system. We study the local stability of equilibrium points and local bifurcation, in particular, by choosing an

Global Bifurcation and a Theorem of Tarantello
Journal of Mathematical Analysis and Applications, 1994 The authors investigate the number of solutions (and their zeros) of the fourth order boundary value problem \(u''''+ cu''= b[(u+ 1)^ +-1]\), \(u(0)= u''(0)= u(r)= u''(r)=0\). To prove their main result, the authors use the method of global bifurcation due to Rabinowitz and the nodal properties of solutions of a second order boundary value problem.

Global bifurcation for the Hénon problem
Communications on Pure and Applied Analysis, 2020 We prove the existence of nonradial solutions for the Hénon equation in the ball with any given number of nodal zones, for arbitrary values of the exponent $α$. For sign-changing solutions, the case $α=0$ -- Lane-Emden equation -- is included. The obtained solutions form global continua which branch off from the curve of radial solutions $p\mapsto u_p$,

Tangency Bifurcations of Global Poincaré Maps
SIAM Journal on Applied Dynamical Systems, 2008 One tool to analyze the qualitative behavior of a periodic orbit of a vector field in $\mathbb{R}^n$ is to consider the Poincaré return map to an $(n-1)$-dimensional section. The image under the Poincaré map of a point on this section that lies near the periodic orbit is obtained by following the flow of the vector field until the next (local ...
