AI总结:

本文研究了线性时不变ODE系统的短时间行为与hypocoercivity指数的关系,通过系统矩阵的hypocoercivity理论提出了一种简洁的表征方法。

摘要:

我们考虑了一类保守-耗散ODE系统,这是Lyapunov稳定的线性时不变ODE系统的一个子类。我们通过系统矩阵的hypocoercivity(理论)来表征渐近稳定的保守-耗散ODE系统。我们的主要结果是用关联的保守-耗散ODE系统的传播算子范数的短时间行为来简洁地表征hypocoercivity指数(一种引入于Achleitner、Arnold和Carlen(2018)的矩阵的代数结构性质)。

英文摘要:

We consider the class of conservative-dissipative ODE systems, which is a subclass of Lyapunov stable, linear time-invariant ODE systems. We characterize asymptotically stable, conservative-dissipative ODE systems via the hypocoercivity (theory) of their system matrices. Our main result is a concise characterization of the hypocoercivity index (an algebraic structural property of matrices with positive semi-definite Hermitian part introduced in Achleitner, Arnold, and Carlen (2018)) in terms of the short time behavior of the propagator norm for the associated conservative-dissipative ODE system.
