Random walks on graphs and spectral radius: part 2

Anush Tserunyan (UIUC Math)

Abstract: We will continue discussing random walks on graphs and their spectral radius, computing that the spectral radius of $\mathbb{Z}^d$ is $1$, whereas it is less than $1$ for a $d$-regular tree with $d \ge 3$. We will then consider another parameter used in studying a given random walk, namely, the expectation of the number of visits to a fixed vertex. This controls the recurrence of the random walk and we will use it to deduce that the simple random walk on $\mathbb{Z}^d$ is recurrent if and only if $d \le 2$.
