We give an exposition of a result of Borell (Commun Math Phys 86:143–147, 1982) that the probability function that Brownian motion hits the inner boundary before time t and before hitting the outer boundary is a space-time quasiconcave function.

凸环中热方程的拟凹性。

我们对Borell的结果进行说明(Commun Math Phys 86:143–147,1982),布朗运动在时间t之前和到达外部边界之前到达内部边界的概率函数是时空拟凹函数。
