On the distribution of $k$ -free numbers on the view point of random walks

Kui Liu, Meijie Lu

In this paper, we investigate the distribution of $k$ -free numbers in a class of $α$ -random walks on the integer lattice $Z$ . In these walks, the walker starts from a non-…

Visible lattice points in higher dimensional random walks and biases among them

Kui Liu, Meijie Lu, Xianchang Meng

For any integers $k \geq 2$ , $q \geq 1$ and any finite set $A = {α_{1}, \dots, α_{q}}$ , where ${ \boldsymbolα_t}=(α_{t,1},\cdots,α_{t,k})~(1\leq t\leq…

$k$ -free lattice points in random walks

Kui Liu, Shunqi Ma

Let $Z^{2}$ be the two-dimensional integer lattice. For an integer $k \geq 1$ , a non-zero lattice point is $k$ -free if the greatest common divisor of its coordinates is a $k$ …

On some sums involving the integral part function

Kui Liu, Jie Wu, Zhishan Yang

Denote by $τ$ k (n), $ω$ (n) and $μ$ 2 (n) the number of representations of n as product of k natural numbers, the number of distinct prime factors of n and the characteristic funct…

A variant of the prime number theorem

Kui Liu, Jie Wu, Zhishan Yang

Let $Λ (n)$ be the von Mangoldt function, and let $[t]$ be the integral part of real number $t$ . In this note, we prove that for any $ε > 0$ the asymptotic formula $$ \sum_{…

Random walks on generalized visible lattice points

Kui Liu, Xianchang Meng

We consider the proportion of generalized visible lattice points in the plane visited by random walkers. Our work concerns the visible lattice points in random walks in three aspec…
