On three open problems in zero-sum Ramsey numbers

Cheng Chi, Jialin He, Quan Sun

Let $K_{N}^{(r)}$ denote the $N$ -vertex complete $r$ -uniform hypergraph. For an $r$ -uniform hypergraph $H$ and an integer $k \geq 2$ , the $k$ -color Ramsey number $R (H, k)$ is the least…

A note on zero-sum Ramsey numbers of complete graphs

Cheng Chi, Jialin He, Fuhong Ma

For a graph $H$ with $3 ∣ e (H)$ , the zero-sum Ramsey number $R (H, Z_{3})$ is the least integer $N$ such that every labeling of the edges of $K_{N}$ by elements of $Z_{3}$ contains a c…

On Zero-sum Ramsey numbers of complete bipartite graphs

Cheng Chi, Jialin He

For an integer $q \geq 2$ and a graph $F$ satisfying $q ∣ e (F)$ , the zero-sum Ramsey number $R (F, Z_{q})$ is the least integer $n$ such that every edge-labeling $w\colon E(K_n…

On zero-sum Ramsey numbers of cycles and wheels

Cheng Chi, Jialin He

For an integer $q \geq 2$ and a graph $F$ with $q ∣ e (F)$ , let $R (F, Z_{q})$ be the least integer $n$ such that every edge-labeling $w : E (K_{n}) \to Z_{q}$ contains a copy of $F$ wh…

Sublinear Edge Fault Tolerant Spanners for Hypergraphs

Jialin He, Nicholas Popescu, Chunjiang Zhu

We initiate the study on fault-tolerant spanners in hypergraphs and develop fast algorithms for their constructions. A fault-tolerant (FT) spanner preserves approximate distances u…

Studies of beauty hadron and non-prompt charm hadron production in pp collisions at $s$ =13 TeV within a transport model approach

Jialin He, Xinye Peng, Xiaoming Zhang +1

In high-energy proton proton ( $pp$ ) collisions at the LHC, non-prompt charm hadrons, originating from beauty hadron decays, provide a valuable probe for beauty quark dynamics, part…
