Hypergraph Ramsey numbers of cliques versus stars

David Conlon, Jacob Fox, Xiaoyu He +3

Let denote the complete -uniform hypergraph on vertices and the -uniform hypergraph on vertices consisting of all edges incid…

Maximal independent sets in clique-free graphs

Xiaoyu He, Jiaxi Nie, Sam Spiro

Nielsen proved that the maximum number of maximal independent sets (MIS's) of size in an -vertex graph is asymptotic to , with the extremal construction a disjoint…

Hat Guessing on Books and Windmills

Xiaoyu He, Yuzu Ido, Benjamin Przybocki

The hat-guessing number is a graph invariant defined by Butler, Hajiaghayi, Kleinberg, and Leighton. We determine the hat-guessing number exactly for book graphs with sufficiently…

Quantum Search with Prior Knowledge

Xiaoyu He, Jialin Zhang, Xiaoming Sun

Search-base algorithms have widespread applications in different scenarios. Grover's quantum search algorithms and its generalization, amplitude amplification, provide a quadratic…

Hat Guessing Numbers of Degenerate Graphs

Xiaoyu He, Ray Li

Recently, Farnik asked whether the hat guessing number of a graph could be bounded as a function of its degeneracy , and Bosek, Dudek, Farnik, Grytczuk and Ma…

On the Baer-Lovász-Tutte construction of groups from graphs: isomorphism types and homomorphism notions

Xiaoyu He, Youming Qiao

Let be an odd prime. From a simple undirected graph , through the classical procedures of Baer (Trans. Am. Math. Soc., 1938), Tutte (J. Lond. Math. Soc., 1947) and Lovász (B…
