The two postdoctoral scholars will be working on separate areas in probability theory. The first investigator will study a number of problems related to Brownian motion: Brownian windings in the plane, connections between Brownian motion and potential theory, properties of the Ornstein - Uhlenbeck process and Brownian sheet, and problems involving strategies for switching between two Brownian motions. The second investigator will study a number of problems in the area of interacting particle systems: asymptotics for the long range contact process, systems involving coexistence of two species in equilibrium, and a model for surface catalysts.

这两位博士后学者将在概率论的不同领域工作。第一个研究者将研究一些与布朗运动有关的问题：平面上的布朗缠绕，布朗运动与位势理论之间的联系，Ornstein-Uhlenbeck过程和布朗单的性质，以及涉及在两个布朗运动之间切换的策略的问题。第二个研究者将研究相互作用粒子系统领域的一些问题：长程接触过程的渐近性，平衡中两种物种共存的系统，以及表面催化剂的模型。
