对于处于不稳定平衡点附近的一维光滑向量场,我们考虑了受小噪声扰动的相关动力学。我们用Malliavin微积分中的重型机械证明了早先证明的一个结果。特别地,我们得到了非典型长出口条件下的出口时间尾部和出口分布的精确的零噪声渐近性。我们还讨论了关于噪声异宿网络中的罕见跃迁的程序。
For a one-dimensional smooth vector field in a neighborhood of an unstable equilibrium, we consider the associated dynamics perturbed by small noise. We give a revealing elementary proof of a result proved earlier using heavy machinery from Malliavin calculus. In particular, we obtain precise vanishing noise asymptotics for the tail of the exit time and for the exit distribution conditioned on atypically long exits. We also discuss our program on rare transitions in noisy heteroclinic networks.
