Density of rainbow triangles and properly colored $K_{4}$ 's

JÃ³zsef Balogh, Peter Bradshaw, Ramon I. Garcia +1

We establish a sharp upper bound on the number of properly $3$ -edge-colored $K_{4}$ 's in graphs with $R$ red, $G$ green and $B$ blue edges. We give a computer-free flag-algebra proof…

Chip games and multipartite graph paintability

Peter Bradshaw, Tianyue Cao, Atlas Chen +6

We study the paintability, an on-line version of choosability, of complete multipartite graphs. We do this by considering an equivalent chip game introduced by Duraj, Gutowski, and…
