摘要翻译:
本文给出了一类随机驱动动力系统的动力学指数$Z$与稳态指数$γ$之间的指数不等式。我们首先导出一个一般的精确不等式,把响应函数和相关函数联系起来,各种指数不等式都是从这个不等式出发的。然后我们区分了两类动力系统,得到了与$z$和$\gamma$有关的不同的和互补的不等式。讨论了这些不等式对许多动力学问题,包括临界动力学和类Kardar-Parisi-Zhang-like问题的结果。

英文摘要:
In this letter we derive exponent inequalities relating the dynamic exponent $z$ to the steady state exponent $\Gamma$ for a general class of stochastically driven dynamical systems. We begin by deriving a general exact inequality, relating the response function and the correlation function, from which the various exponent inequalities emanate. We then distinguish between two classes of dynamical systems and obtain different and complementary inequalities relating $z$ and $\Gamma$. The consequences of those inequalities for a wide set of dynamical problems, including critical dynamics and Kardar-Parisi-Zhang-like problems are discussed.
