Towards the Erdős matching conjecture for 4-uniform hypergraphs: stability and applications

Peter Frankl, Hongliang Lu, Jie Ma +1

A famous conjecture of Erdős asserts that for , the maximum number of edges in an -vertex -uniform hypergraph without pairwise disjoint edges is $\max\{\binom{n…

Q-DiT4SR: Exploration of Detail-Preserving Diffusion Transformer Quantization for Real-World Image Super-Resolution

Xun Zhang, Kaicheng Yang, Hongliang Lu +3

Recently, Diffusion Transformers (DiTs) have emerged in Real-World Image Super-Resolution (Real-ISR) to generate high-quality textures, yet their heavy inference burden hinders rea…

Anti-Ramsey Number of Stars in 3-uniform hypergraphs

Hongliang Lu, Xinyue Luo, Xinxin Ma

An edge-colored hypergraph is called \emph{a rainbow hypergraph} if all the colors on its edges are distinct. Given two positive integers and an -uniform hypergraph $\math…

Eigenvalues and factors: a survey

Dandan Fan, Huiqiu Lin, Hongliang Lu +1

A factor of a graph is a spanning subgraph satisfying some given conditions. An earlier survey of factors can be traced back to the Akiyama and Kano [J. Graph Theory, 1985, 9: 1-42…

A characterization on orientations of graphs avoiding given lists on out-degrees

Xinxin Ma, Hongliang Lu

Let be a graph and be a set function. The graph is said to be \emph{F-avoiding} if there exists an orientation of such that for…
