偶数维Wiener香肠期望体积的渐近展开

Asymptotic expansion of the expected volume of the Wiener sausage in even dimensions

Yuji Hamana

摘要:

我们考虑布朗运动的维纳香肠时间$t$与一个封闭的球在偶数维的情况下。我们得到了大$t$的Wiener香肠的期望体积的渐近展开。结果表明,该展开式具有许多$\log$项,这些项在奇维情况下不出现。

英文摘要:

We consider the Wiener sausage for a Brownian motion up to time $t$ associated with a closed ball in even dimensional cases. We obtain the asymptotic expansion of the expected volume of the Wiener sausage for large $t$. The result says that the expansion has many $\log$ terms, which do not appear in odd dimensional cases.
