The Kelmans-Seymour conjecture Yu, Xingxing


Seymour and, independently,  Kelmans conjectured that every 5-connected non-planar  graph contains a subdivision of $K_5$. We have recently proved this conjecture. I will give a sketch of our proof, and mention several related problems. Joint work with D. He and Y. Wang.
