Rose McCarty, Circle graphs are polynomially chi-bounded

April 26 Friday @ 4:00 PM - 5:00 PM

Room B232, IBS (기초과학연구원)

Circle graphs are the intersection graphs of chords on a circle; vertices correspond to chords, and two vertices are adjacent if their chords intersect. We prove that every circle graph with clique number k has chromatic number at most $4k^2$. Joint with James Davies.
