There will be three courses of around 10 hours each, covering different proofs of the Hanna Neumann conjecture and generalizations. The courses are the following:

• Joel Friedman, "A course on graph theory, sheaves on graphs, and the Hanna Neumann Conjecture".
• Andrei Jaikin Zapirain, "Approximation by subgroups of finite index and the Hanna Neumann conjecture".
• Yago Antolín Pichel, "Intersections of  subgroups of free groups".

Apart from these courses, there will be some contributed talks in the workshop. Here is the programme and abstracts of the talks.

The workshop will be held in room 0.19S on Mondays, Tuesdays, Thursdays and Fridays and in room 0.20S on Wednesdays.
