The Tangential Center-Focus Problemee . in terms of .. This is a very hard problem, but Arnold has suggested a “Weak Hilbert’s 16th problem” which seems far more tractable: to find a bound on the number of limit cycles which can bifurcate from a first-order perturbation of a Hamiltonian system, . where the Hamiltonian, ., is a polyno撤退 发表于 2025-3-26 15:21:27
Holonomy and the Lotka-Volterra Systemood of an invariant curve. This object, roughly speaking, is the nonlinear analog to the monodromy of the solutions of a linear differential equation as they turn around a singular point. Alternatively, it can be thought of as a kind of Poincaré return map for foliations.植物学 发表于 2025-3-26 18:54:51
Other Approachesponents of the center variety by finding their intersections with specific subsets of parameter space and then showing that the type of center is “rigid”. In the second approach, we try to see the consequences of a center on its bounding graphic. Monodromytype arguments play an implicit role in both
