摘要:

我们分别分析了布朗桥在子区间$[0,t_1]$和整个区间$[0,t]$上实现的部分最大值$m$和全局最大值$M$之间的联合分布和时间相关性。我们确定三个概率分布函数:两个最大值的联合分布$P(m,M)$;部分最大值的分布$P(m)$;和最大值之间的间隙的分布$Π(G)$,$G = M-m$。我们目前的确切结果,这些分布的时刻和量化的时间之间的相关性$m$和$M$通过计算皮尔逊相关系数。

英文摘要:

We analyze the joint distributions and temporal correlations between the partial maximum $m$ and the global maximum $M$ achieved by a Brownian Bridge on the subinterval $[0,t_1]$ and on the entire interval $[0,t]$, respectively. We determine three probability distribution functions: The joint distribution $P(m,M)$ of both maxima; the distribution $P(m)$ of the partial maximum; and the distribution $Π(G)$ of the gap between the maxima, $G = M-m$. We present exact results for the moments of these distributions and quantify the temporal correlations between $m$ and $M$ by calculating the Pearson correlation coefficient.
