摘要:
统计力学中的Mori-Zwanzig形式主义被用于估计非线性动力系统解中因分辨率不足引起的不确定性。概述了一种通用方法,并应用于一个简单例子。描述不确定性的噪声项被发现既非马尔可夫也不高斯。论证了这种情形是普遍的。
英文摘要:
The Mori-Zwanzig formalism of statistical mechanics is used to estimate the uncertainty caused by underresolution in the solution of a nonlinear dynamical system. A general approach is outlined and applied to a simple example. The noise term that describes the uncertainty turns out to be neither Markovian nor Gaussian. It is argued that this is the general situation.
