Multicolor Ramsey and list Ramsey numbers for star-like trees

Qinghong Zhao, Yaping Mao, Xiangqian Zhou

For a graph \(H\), the \(k\)-color Ramsey number \(r(H;k)\) is the least integer \(N\) such that every \(k\)-edge-coloring of \(K_N\) contains a monochromatic copy of \(H\). A \(k\…

Ramsey Achievement Games on Graphs : Algorithms and Bounds

Xiumin Wang, Zhong Huang, Xiangqian Zhou +2

In 1982, Harary introduced the concept of Ramsey achievement game on graphs. Given a graph with no isolated vertices. Consider the following game played on the complete graph $…

Some novel minimax results for perfect matchings of hexagonal systems

Xiangqian Zhou, Heping Zhang

The anti-forcing number of a perfect matching of a graph is the minimum number of edges of whose deletion results in a subgraph with a unique perfect matching , deno…

Forcing and anti-forcing polynomials of perfect matchings of a pyrene system

Kai Deng, Saihua Liu, Xiangqian Zhou

The forcing number of a perfect matching of a graph was introduced by Harary et al., which originated from Klein and Randić's ideal of innate degree of freedom of Kekulé structure…

DP-4-colorability of two classes of planar graphs

Lily Chen, Runrun Liu, Gexin Yu +2

DP-coloring (also known as correspondence coloring) is a generalization of list coloring introduced recently by Dvořák and Postle (2017). In this paper, we prove that every planar…

The strong chromatic index of -bipartite graphs

Mingfang Huang, Gexin Yu, Xiangqian Zhou

A strong edge-coloring of a graph is a partition of its edge set into induced matchings. We study bipartite graphs with one part having maximum degree at most and…

Triangle-roundedness in matroids

João Paulo Costalonga, Xianqiang Zhou

A matroid is said to be triangle-rounded in a class of matroids if each -connected matroid with a triangle and an -minor has an -m…

Tars: Timeliness-aware Adaptive Replica Selection for Key-Value Stores

Wanchun Jiang, Liyuan Fang, Haiming Xie +2

In current large-scale distributed key-value stores, a single end-user request may lead to key-value access across tens or hundreds of servers. The tail latency of these key-value…

A Maximum Resonant Set of Polyomino Graphs

Heping Zhang, Xiangqian Zhou

A polyomino graph is a connected finite subgraph of the infinite plane grid such that each finite face is surrounded by a regular square of side length one and each edge belong…
