SUMMARY:A brief (pre)history of perfectoid spaces - Kiran Kedlaya (Univers

DESCRIPTION:Classical Hodge theory can be interpreted as the relationship 
 between\nthe topology of manifolds and the cohomology of differential form
 s. In\n  arithmetic geometry\, the parallel subject of p-adic Hodge theory
  relates\n   Galois actions on etale cohomology to differential forms. Rec
 ently\, this\n    subject has been overturned by a series of developments 
 culminating in\n   the construction of a class of objects called "perfecto
 id spaces".\n     Without trying to give too many formal definitions\, I w
 ill indicate some\n     of the key ideas that go into the theory\; as time
  permits\, I'll also\n    mention some of the directions in which the work
  of Scholze carries this\n    theory far beyond its point of origin.
