报告内容：Visible lattice points is one of the important research objects in number theory. In the previous studies of classical analytic number theory, the density of the corresponding lattice points is considered from the deterministic point of view for various counting problems of visible lattice points. In this talk, we consider the visible points from the perspective of random walks. Precisely, we study the distribution of the visible lattice points in certain perturbed P\'{o}lya's walk on $\mathbb{Z}^k$, we prove that the density of visible lattice points in a perturbed P\'{o}lya's walk is almost surely $1/\zeta(k)$, where $\zeta(s)$ denotes the Riemann zeta function. This work combines tools from both number theory and probability theory.
