Graph Decomposition - A proof of Ringel's Conjecture
Abstract: Decomposing graphs into smaller subgraphs is a classical problem with a long and rich history and many appealing results and conjectures. One of the most outstanding conjecture from the field is Ringel's conjecture (1963), stating that the complete graph $K_{2n+1}$ on (2n+1) vertices can be decomposed into copies of every tree on $n$ edges for every $n \in \mathbb{N}$. The main result presented in this talk is a recent proof of Ringel's conjecture (for sufficiently large $n$) by Montgomery, Pokrovskiy, and Sudakov.
