Derived category in algebraic geometry
Webations on their categories of sheaves. 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. (When X is a familiar scheme or stack, QC(X) is an enriched version of the usual quasi-coherent derived category Dqc(X).) We show that for a broad ... WebApr 10, 2024 · In particular, we obtain the compact generation of the ∞ $\infty$-category of quasi-coherent sheaves and the existence of compact perfect complexes with prescribed support for such stacks. We extend these results to derived algebraic geometry by studying the relationship between derived and spectral algebraic stacks.

WebE 2 p q = R p F ( R q G M) ⇒ R p + q F ∘ G M. By constrast, in the derived category world we see a composition law. R F ∘ R G ≅ R F ∘ G. For 3 or more functors, the last formula generalizes in the obvious way. On the spectral sequence side, we get something too horrible to comtemplate. Well no, let me comtemplate it: WebThe main idea of derived categories is simple: work with complexes rather than their (co)homology. We will take simple examples from algebraic geometry to demonstrate why one might want to do this, then examples from algebraic topology to show that the ideas and structure are already familiar. (The link between the
WebIn the 1970s, Beilinson, Gelfand, and Gelfand discovered that a derived category of an algebraic variety may be equivalent to that of a finite-dimensional non-commutative algebra, and Mukai found that there are non-isomorphic algebraic varieties that have equivalent derived categories.
