Edge-Number Bounds for the Inversion Diameter of Graphs

Jiawen Bo, Anqi Li, Xiaopan Lian +1

The inversion of a set $X$ of vertices in an oriented graph reverses every arc with both endpoints in $X$ . The inversion graph $I (G)$ of a graph $G$ has the labelled orientations o…

The multicolour size Ramsey number of a path

Csongor Beke, Anqi Li, Julian Sahasrabudhe

In this paper, we determine the $r$ -colour size Ramsey number of the path $P_{k}$ , up to constants. In particular, for every fixed $r \geq 2$ and $k \geq 100 lo g r$ , we have \[ \wide…

Edge inducibility via local directed graphs

Ting-Wei Chao, Asaf Cohen Antonir, Anqi Li +1

In this paper we introduce the edge inducibility problem. This is a common refinement of both the well known Kruskal--Katona theorem and the inducibility question introduced by Pip…

Unbalanced Zarankiewicz problem for bipartite subdivisions with applications to incidence geometry

Lili Ködmön, Anqi Li, Ji Zeng

For a bipartite graph $H$ , its linear threshold is the smallest real number $σ$ such that every bipartite graph $G = (U ⊔ V, E)$ with unbalanced parts $∣ V ∣ ≳ ∣ U ∣^{σ}$ and…

Uncommon linear systems of two equations

Dingding Dong, Anqi Li, Yufei Zhao

A system of linear equations $L$ is common over $F_{p}$ if, as $n \to \infty$ , any 2-coloring of $F_{p}^{n}$ gives asymptotically at least as many monochromatic solutions…

Dynamics of Pop-Tsack Torsing

Anqi Li

For a finite irreducible Coxeter group $(W, S)$ with a fixed Coxeter element $c$ and set of reflections $T$ , Defant and Williams define a pop-tsack torsing operation $\mathrm{Popt}\…
