AI总结:

本研究对临界及超临界漂移下、几乎必然局部有限的分支布朗运动(BBM)的不动点及其吸引域进行了完整刻画,未采用有限强度或有限顶端粒子等额外假设。

AI中文摘要:

我们对临界及超临界漂移下的分支布朗运动(BBM)的不动点进行了完整刻画,仅要求其几乎必然为局部有限,不额外假设有限强度(Kabluchko,2012)或有限顶端粒子(Chen-Garban-Shekhar,2023)条件。我们还完整刻画了BBM不动点的吸引域。

英文摘要:

We give a full characterization of the fixed points of Branching Brownian motion with critical and supercritical drifts under no additional assumptions besides it being locally finite almost surely. In particular, we do not assume finite intensity (Kabluchko, 2012) or the finite top particle (Chen-Garban-Shekhar, 2023) conditions. We also give a full characterization of the domain of attraction of the fixed points of BBM.
