Global Hopf Bifurcation Analysis of a Neuron Network Model with Time Delays,rmal form method and center manifold theorem. To show that periodic solutions exist away from the bifurcation points, we establish that local Hopf branches globally extend for arbitrarily large delays.作者: aptitude 時(shí)間: 2025-3-22 07:13
Instability of Low Density Supersonic Waves of a Viscous Isentropic Gas Flow Through a Nozzle, unstable; more precisely, we will establish the existence of positive eigenvalues for the linearization along such waves. The result is achieved via a center manifold reduction of the eigenvalue problem. The reduced eigenvalue problem is then studied in the framework of the Sturm–Liouville Theory.作者: 跳動(dòng) 時(shí)間: 2025-3-22 09:33

Littlewood Problem for a Singular Subquadratic Potential,We consider a periodically forced singular oscillator in which the potential has subquadratic growth at infinity and admits a singularity. Using Moser’s twist theorem of invariant curves, we show the existence of quasiperiodic solutions. This solves the Littlewood problem on the boundedness of all solutions for such a system.作者: Irritate 時(shí)間: 2025-3-24 22:31 作者: CHAFE 時(shí)間: 2025-3-25 02:39

Bifurcation of Limit Cycles from a Non-Hamiltonian Quadratic Integrable System with Homoclinic LoopIn this chapter, we study quadratic perturbations of a non-Hamiltonian quadratic integrable system with a homoclinic loop. We prove that the perturbed system has at most two limit cycles in the finite phase plane, and the bound is exact. The proof relies on an estimation of the number of zeros of related Abelian integrals.作者: Perennial長(zhǎng)期的 時(shí)間: 2025-3-25 14:04
