利用Schr odinger型算子的主本征值确定了欧氏空间中分支布朗运动的最大位移的长时间行为和尾概率的精确阶.为了建立我们的结果,我们证明了Feynman-Kac半群的尖锐且局部一致的增长序。
We determine the long time behavior and the exact order of the tail probability for the maximal displacement of a branching Brownian motion in Euclidean space in terms of the principal eigenvalue of the associated Schr\"odinger type operator. To establish our results, we show a sharp and locally uniform growth order of the Feynman-Kac semigroup.
