Abstract

In this paper, we apply the theory of Bridgeland stability conditions, which was originated from string theory, to study the derived category of coherent sheaves on Fargues--Fontaine curves. This leads us to consider the quasi-coherent sheaves O(θ±) via the convergents of an irrational number θ. We define the continuum envelop QCoh(XFF) to be the smallest abelian subcategory in QCoh(XFF) containing Coh(XFF) and O(θ±). We study the homological algebra of QCoh(XFF) via Farey diagrams. We show that the homological property of O(θ±) depends heavily on the arithmetic property of θ. The Fargues--Fontaine curves present strong similarity with complex elliptic curves in this point of view.
