Perfectoid spaces
Abstract
We introduce a certain class of socalled perfectoid rings and spaces, which give a natural framework for Faltings' almost purity theorem, and for which there is a natural tilting operation which exchanges characteristic 0 and characteristic p. We deduce the weightmonodromy conjecture in certain cases by reduction to equal characteristic.
