我们考虑Vlasov-HMF(Hamiltonian Mean-Field)模型。我们认为解决方案在一个小的Sobolev附近的空间均匀的状态满足线性化的稳定性标准(彭罗斯标准)。我们证明了这些解对一个修正态的散射行为,这意味着具有多项式阻尼率的非线性朗道阻尼效应。
We consider the Vlasov-HMF (Hamiltonian Mean-Field) model. We consider solutions starting in a small Sobolev neighborhood of a spatially homogeneous state satisfying a linearized stability criterion (Penrose criterion). We prove that these solutions exhibit a scattering behavior to a modified state, which implies a nonlinear Landau damping effect with polynomial rate of damping.
