SUMMARY:Degree conditions forcing oriented cycles - Andrzej Grzesik (Jagie
 llonian University)
DTSTART:20190523T133000Z

UID:TALK120352@talks.cam.ac.uk
CONTACT:Andrew Thomason
DESCRIPTION:Motivated by the longstanding Caccetta-Häggkvist Conjecture\,
  Kelly\, Kühn and Osthus made a conjecture on the minimal semi-degree for
 cing the appearance of a directed cycle of a given length\, and proved it 
 for cycles of length not divisible by 3. In the talk we will present an ov
 erview of a\nproof of all the remaining cases of their conjecture with the
  optimal semi-degree threshold. This is joint work with Roman Glebov and J
 an Volec.\n
