Marcin Briański gave a talk at the Discrete Math Seminar on the existence of large Burling graphs or large complete graphs on string graphs of very large chromatic number

On April 22, 2025, Marcin Briański from Jagiellonian University in Krakóv, Poland gave a talk on the existence of large Burling graphs or large complete graphs on string graphs of very large chromatic number at the Discrete Math Seminar. The title of his talk was “Burling Graphs as (almost) universal obstacles to 𝜒-boundedness“.
