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

Kui Liu, Meijie Lu, Xianchang Meng

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

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…

Distinct distances on hyperbolic surfaces

Xianchang Meng

For any cofinite Fuchsian group , we show that any set of points on the hyperbolic surface determines $\geq C_Γ \fr…

Erdős distinct distances in hyperbolic surfaces

Zhipeng Lu, Xianchang Meng

In this paper, we introduce the notion of "geodesic cover" for Fuchsian groups, which summons copies of fundamental polygons in the hyperbolic plane to cover pairs of representativ…

Visible lattice points along curves

Kui Liu, Xianchang Meng

This paper concerns the number of lattice points in the plane which are visible along certain curves to all elements in some set S of lattice points simultaneously. By proposing th…

Summatory function of the number of prime factors

Xianchang Meng

We consider the summatory function of the number of prime factors for integers over arithmetic progressions. Numerical experiments suggest that some arithmetic progression…
