Although chaotic attractors for autonomous dynamical systems show sensitive dependence on initial conditions, they also typically support a physical or natural measure that characterizes the statistical behavior of almost all initial conditions near the attractor with respect to a background measure such as Lebesgue. In this paper, we identify conditions under which a nonautonomous system that limits as to an autonomous system with a physical measure is guaranteed to possess a “nonautonomous physical measure” that limits to the physical measure of the autonomous system.

渐进自治动力系统的物理测量
尽管自主动力系统的混沌吸引子表现出对初始条件的敏感依赖性,但它们通常也支持物理或自然测量,该测量表征吸引子附近几乎所有初始条件相对于背景测量(例如勒贝格)的统计行为。在本文中,我们确定了非自治系统限制为的条件具有物理量度的自治系统保证拥有限制于自治系统的物理量度的“非自治物理量度”。
