Room B109 IBS (기초과학연구원)Jungho Ahn (안정호), A coarse Erdős-Pósa theorem for constrained cycles
Room B332 IBS (기초과학연구원)An induced packing of cycles in a graph is a set of vertex-disjoint cycles such that the graph has no edge between distinct cycles of the set. The classic Erdős-Pósa theorem …

Sepehr Hajebi, The pathwidth theorem for induced subgraphs
Room B332 IBS (기초과학연구원)We present a full characterization of the unavoidable induced subgraphs of graphs with large pathwidth. This consists of two results. The first result says that for every forest H, every …
Irene Muzi, An elementary bound for Younger’s conjecture
Room B332 IBS (기초과학연구원)In 1996, Reed, Robertson, Seymour and Thomas proved Younger's Conjecture, which states that for all directed graphs D, there exists a function f such that if D does not contain …
Johannes Carmesin, Open problems in graph theory
Room B332 IBS (기초과학연구원)Since the proof of the graph minor structure theorem by Robertson and Seymour in 2004, its underlying ideas have found applications in a much broader range of settings than their …
