| contents | 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 $\mathcal{O}(θ^{\pm})$ via the convergents of an irrational number $θ$.
We define the continuum envelop $\mathrm{QCoh}_{\mathbb{R}}(X_{FF})$ to be the smallest abelian subcategory in $\mathrm{QCoh}(X_{FF})$ containing $\mathrm{Coh}(X_{FF})$ and $\mathcal{O}(θ^{\pm})$. We study the homological algebra of $\mathrm{QCoh}_{\mathbb{R}}(X_{FF})$ via Farey diagrams. We show that the homological property of $\mathcal{O}(θ^{\pm})$ depends heavily on the arithmetic property of $θ$. The Fargues--Fontaine curves present strong similarity with complex elliptic curves in this point of view. |
