Derived category in algebraic geometry
Webcategory of quasi-coherent sheaves on even such benign objects as algebraic stacks was quite awkward (see [LM]). Essentially, in the past, each time one needed to construct a triangulated category, one had to start from an abelian category, take its derived category, and then perform some manipulations on it in order to obtained the desired one. WebWe surveyed the theory of algebraic stacks (fibered categories and descent, quasi-coherent sheaves, quotient stacks, deformation theory, and Artin's criteria, Tannaka duality), then discussed more recent advances (the etale local structure theorems of Alper, Hall, and Rydh, and the results of beyond GIT), and applied these methods to the moduli …

We work in the general setting of derived algebraic geometry: our basic objects are derived stacks X and their ∞-categories QC(X) of quasi-coherent sheaves.
