本文给出了对称零程过程谱隙的一个下界。在速率函数的某些条件下,我们证明了对于定域在大小为ndd的立方体上的动力学,差距收缩为n-2,与密度无关.我们遵循陆和丘,其中一个类似的光谱间隙证明了川崎动力学概述的方法。
We give a lower bound on the spectral gap for symmetric zero-range processes. Under some conditions on the rate function, we show that the gap shrinks as n -2 , independent of the density, for the dynamics localized on a cube of size n d . We follow the method outlined by Lu and Yau, where a similar spectral gap is proved for Kawasaki dynamics.
