无限程Gibbs测度的完美模拟及其与有限程近似的耦合

Perfect simulation of infinite range Gibbs measures and coupling with their finite range approximations

Antonio Galves, Eva Loecherbach, Enza Orlandi

摘要:

在本文中,我们解决的问题,完全抽样的吉布斯措施与无限范围的相互作用和完全抽样的措施连同其有限范围的近似。我们解决这些问题,通过引入一个完美的模拟算法的措施和耦合措施。该算法适用于一般的吉布斯相互作用的要求下的尾巴的相互作用。因此,我们得到一个上界的错误,我们从一个有限范围的近似采样时,而不是真正的无限范围的措施。

英文摘要:

In this paper we address the questions of perfectly sampling a Gibbs measure with infinite range interactions and of perfectly sampling the measure together with its finite range approximations. We solve these questions by introducing a perfect simulation algorithm for the measure and for the coupled measures. The algorithm works for general Gibbsian interaction under requirements on the tails of the interaction. As a consequence we obtain an upper bound for the error we make when sampling from a finite range approximation instead of the true infinite range measure.
