題目： Large deviation estimates related to arcsine laws for the last visit times 

概要：L\'evy's arcsine law for one-dimensional Brownian motion is a classical result in probability theory. Among various generalizations of the arcsine law, we focus on the Dynkin--Lamperti theorem, which is a distributional limit theorem for the position of a subordinator (i.e., an increasing L\'evy process) just before it exceeds a level $t$, as $t\to0+$ or $t\to\infty$. In this talk we recall the Dynkin--Lamperti theorem and then present related large deviation estimates as our main results. Furthermore we demonstrate that our main results can be applied to the last time the Brownian motion on the Sierpinski gasket visits the starting point. This talk is based on joint work with Takahiro Mori (Kyoto Institute of Technology) and Kei Noba (The University of Osaka).
