User:Holger Brenner/Hilbert-Kunz multiplicity/Talk in Luminy (2011)

We want to discuss some situations where the answer to these problems is known. A typical feature of Hilbert-Kunz theory is that in special situations there is sometimes a special interpretation of the Hilbert-Kunz multiplicity, and then a positive answer to all questions above follow from this. If there is no such interpretation, then usually nothing is known.
