The list coloring number of uncrowded hypergraphs

Jing Yu, Junchi Zhang

We prove that for every fixed integer and every , every sufficiently large finite uncrowded -uniform hypergraph of maximum degree has list chro…

On independent sets in uncrowded uniform hypergraphs

Jing Yu, Junchi Zhang

We prove an average-degree lower bound on the independence number of uncrowded uniform hypergraphs. For every fixed and every , there exists such th…

Strong marker sets for arbitrary generating sets of

Jing Yu

Gao and Wang proved a strong clopen marker theorem for finite generating sets of under the assumption that each generator has support of size either or . We sh…

Submodular flows and extreme flows on measurable spaces

Jing Yu, Junchi Zhang, Mingyang Zhou

The theory of submodular flows, introduced by Edmonds and Giles, is a cornerstone of combinatorial optimization, unifying network flows, matroid intersections and directed cut cove…

Borel Local Lemma: arbitrary random variables and limited exponential growth

Anton Bernshteyn, Jing Yu

The Lovász Local Lemma (the LLL for short) is a powerful tool in probabilistic combinatorics that is used to verify the existence of combinatorial objects with desirable propertie…

Hypergraph independence bounds: from maximum degree to average degree

Jing Yu, Junchi Zhang

We prove a transfer theorem for hereditary classes of -uniform hypergraphs. Let be such a class, and for write and for the maxim…
