Entropy Transference for Rainbow--Free Colourings of Random Graphs

Mengyu Cao, Mei Lu, Haixiang Zhang

Let be a fixed graph with that contains two adjacent edges, and let be fixed. We establish an entropy-transference principle for rainbow--free edge…

Convex Transference for Degree Powers in Extremal Set Systems

Mengyu Cao, Mei Lu, Haixiang Zhang

The paper introduces a discrete two‑moment interpolation technique to bound sums of degree powers in intersecting families and shows that full star families uniquely maximize these…

Projective Ore-Degree Conditions for Intersection Theorems in Vector Spaces

Mengyu Cao, Mei Lu, Xuyang Yan +1

The paper introduces a projective Ore-degree measure for families of k‑dimensional subspaces over a finite field and proves sharp analogues of the Erdős–Ko–Rado and Hilton–Milner i…

Matchings and Near-Optimal 2-Factor Packings in Percolated Vertex-Transitive Graphs

Mengyu Cao, Mei Lu, Xiamiao Zhao

Let be a connected simple vertex-transitive graph on vertices with degree , and let be the random spanning subgraph obtained by retaining each edge of independ…

On degree bounds of -uniform hypergraphs with bounded matching number

Haixiang Zhang, Mengyu Cao, Mei Lu

The paper establishes degree sequence and Ore-degree conditions that guarantee a k‑uniform hypergraph contains a matching of a given size, improving previous bounds and showing the…

Generalizations of the Erdős Matching Conjecture for the -Matching Number

Mengyu Cao, Mei Lu, Haixiang Zhang

The paper determines the maximum number of edges in a k‑uniform hypergraph with a prescribed t‑matching number, extending the Erdős Matching Conjecture, and also identifies the sec…
