An exponential improvement for Ramsey lower bounds

Jie Ma, Wujie Shen, Shengjie Xie

We prove a new lower bound on the Ramsey number $r (ℓ, C ℓ)$ for any constant $C > 1$ and sufficiently large $ℓ$ , showing that there exists $ε = ε (C) > 0$ s…

Closed geodesics on hyperbolic surfaces with few intersections

Wujie Shen

We prove that, if a closed geodesic $Γ$ on a complete finite type hyperbolic surface has at least 2 self-intersections, then the length of $Γ$ has an lower bound $2 lo g (5 + 26)$ …

Nonsimple closed geodesics with given intersection number on hyperbolic surfaces

Wujie Shen

We prove that the minimal length of a closed geodesic with self-intersection number $k$ on any finite-type hyperbolic surface is $2 cosh^{- 1} (1 + 2 k)$ for $k > 1750$ . This improves the…

Minimal length of nonsimple closed geodesics on hyperbolic surfaces

Wujie Shen, Jiajun Wang

In the present paper, we show that the minimal length of closed geodesics on finite-type hyperbolic surfaces with self-intersection number $k$ has order $2 lo g k$ as $k$ gets large…
