A note on tree-cycle Ramsey numbers

Ting Huang, Yanbo Zhang, Yaojun Chen

Let denote the Ramsey number of a tree on vertices versus a cycle of length . Burr, Erdős, Faudree, Rousseau, and Schelp (1982) asked for the least…

Odd covers for complete graphs and complete 3-graphs

Ting Huang, Jiabao Yang, Yaojun Chen

The Graham-Pollak theorem says that one needs at least complete bipartite graphs to cover each edge of a complete graph on vertices exactly once. The odd cover…

On the threshold Ramsey multiplicity conjectures for paths and even cycles

Ting Huang, Jiabao Yang, Yaojun Chen

The Ramsey number of a graph is the minimum positive integer such that every red/blue edge-coloring of the complete graph on vertices contains a monochroma…

Ramsey numbers of sparse graphs versus disjoint books

Ting Huang, Yanbo Zhang, Yaojun Chen

Let denote a book on vertices and be vertex-disjoint 's. Let be a connected graph with vertices and at most edges, where is a con…
