On the rainbow Cameron-ErdÅs problem with respect to generalized Sidon sets of multidimensional grids

Xihe Li, Runshan Wang

For positive integers $n$ , $d$ , $k$ and $h$ , let $[n]^{d}$ be the $d$ -dimensional grid of order $n$ , and we refer to the equation $\sum_{i=1}^{h}x_{1,i}=\cdots =\sum_{i=1}^{h}x_{k,i}…

Constrained Ramsey numbers for rainbow $P_{5}$

Xihe Li, Xiangxiang Liu

Given a graph $H$ and a positive integer $k$ , the {\it $k$ -colored Ramsey number} $R_{k} (H)$ is the minimum integer $n$ such that in every $k$ -edge-coloring of the complete graph $K_…

On the multicolor TurÃ¡n conjecture for color-critical graphs

Xihe Li, Jie Ma, Zhiheng Zheng

A {\it simple $k$ -coloring} of a multigraph $G$ is a decomposition of the edge multiset as a disjoint sum of $k$ simple graphs which are referred as colors. A subgraph $H$ of a mul…
