摘要

我们考虑了伴随维纳过程和随机游走轨迹的拉紧弦的动能。在一定的带宽假设下，证明了带内随机游走的拉紧弦的能量与前面在Wiener过程和固定带宽下证明的一样，满足强大数定律。对维纳过程也得到了新的结果。2020年数学学科分类:小学60G15;二级60G17、60F15。

Energy of taut strings accompanying random walk

We consider the kinetic energy of the taut strings accompanying trajectories of a Wiener process and a random walk. Under certain assumptions on the band width, it is shown that the energy of a taut string accompanying a random walk within a band satisfies the same strong law of large numbers as proved earlier for a Wiener process and a fixed band width. New results for Wiener processes are also obtained. 2020 Mathematics Subject Classification: Primary 60G15; Secondary 60G17, 60F15.
