Abstract: Kelmans and Seymour independently conjectured in the 1970s that every 5-connected nonplanar graph contains a subdivision of $K_5$. Ma and Yu proved that this conjecture holds for graphs containing $K_4^-$. I will discuss recent progress we made on this conjecture. This is a joint work with Dawei He and Yan Wang.
