分支布朗运动在两个温度下的重叠分布

The overlap distribution at two temperatures for the branching Brownian motion

Benjamin Bonnefont

摘要:

研究了分支布朗运动中两个粒子在吉布斯测度下在两个温度下的重叠分布。我们首先证明了重叠分布的收敛性使用的极值过程的Bovier和Hartung得到的扩展收敛。然后,我们证明了在不同温度下选择的两个点的平均重叠严格小于在德里达的随机能量模型。最后一个结果的证明是通过描述Aïdékon、Berestycki、Brunet和Shi得到的装饰点过程来实现的。据我们所知,这是第一次使用这种描述。

英文摘要:

We study the overlap distribution of two particles chosen under the Gibbs measure at two temperatures for the branching Brownian motion. We first prove the convergence of the overlap distribution using the extended convergence of the extremal process obtained by Bovier and Hartung. We then prove that the mean overlap of two points chosen at different temperatures is strictly smaller than in Derrida's random energy model. The proof of this last result is achieved with the description of the decoration point process obtained by Aïdékon, Berestycki, Brunet and Shi. To our knowledge, it is the first time that this description is being used.
