一类相对论扩散方程的中心极限定理

Central Limit Theorem for a Class of Relativistic Diffusions

Jürgen Angst, Jacques Franchi

摘要:

两个类似的闵可夫斯基扩散已被考虑,一方面是由Barbachoux,Debbasch,Malik和Rivet([BDR1],[BDR2],[BDR3],[DMR],[DR]),另一方面是由Dunkel和Hänggi([DH1],[DH2])。我们在这里解决两个问题,分别在[DR]和([DH1],[DH2])中提出,关于这种扩散的渐近行为。更一般地,我们建立了一个中心极限定理的一类闵可夫斯基扩散,其中上述两个。因此,我们纠正了[DH1]中部分错误的猜测。

英文摘要:

Two similar Minkowskian diffusions have been considered, on one hand by Barbachoux, Debbasch, Malik and Rivet ([BDR1], [BDR2], [BDR3], [DMR], [DR]), and on the other hand by Dunkel and Hänggi ([DH1], [DH2]). We address here two questions, asked in [DR] and in ([DH1], [DH2]) respectively, about the asymptotic behaviour of such diffusions. More generally, we establish a central limit theorem for a class of Minkowskian diffusions, to which the two above ones belong. As a consequence, we correct a partially wrong guess in [DH1].
