guide to noncommutative algebraic geometry literature

This entry provides commented references on the topic of derived noncommutative algebraic geometry.

The original representability theorem: every fully faithful triangulated functor between the derived categories of perfect complexes on two smooth projective varieties is representable by some integral kernel (i.e. is a Fourier-Mukai functor).

If a smooth projective variety has the property that its canonical sheaf is ample? or anti-ample, then one may reconstruct it up to isomorphism from its bounded derived category of coherent sheaves.

A criterion for the equivalence of the derived categories of coherent sheaves on two abelian varieties.

The bounded derived category of coherent sheaves on a smooth projective variety admits a strong generator.

The homotopy category of the model category of dg-categories, where weak equivalences are quasi-equivalences, is studied. It is shown to admit internal homs and the morphism sets are in bijection with right quasi-representable bimodules. Among other applications is a dg-version of Orlov’s representability theorem: it is shown that morphisms between the dg-categories of perfect complexes on smooth proper schemes are in bijection with perfect complexes on the product. An analogous statement for quasi-coherent complexes? is also shown.

The Chow motive of a smooth projective variety may be reconstructed up to Tate twists from the bounded derived category of coherent sheaves.

An (infinity,1)-categorical version of Orlov’s representability theorem, which is further generalized to (smooth proper) derived stacks.

Uniqueness results are established for dg-enhancements of triangulated categories. In particular the results are applied to the derived categories of perfect complexes, coherent sheaves, quasi-coherent sheaves, on schemes. This is then used to deduce from (Toen 2004) representability theorems on the level of triangulated categories, in the non-smooth case.

Describes how to glue two dg-categories in such a way that the homotopy category of the result has a semiorthogonal decomposition into two components, which are the respective homotopy categories of the original dg-categories.

If an admissible subcategory of the bounded derived category of coherent sheaves on a smooth projective variety is a phantom?, has vanishing Hochschild homology and Grothendieck group, then its noncommutative motive vanishes. In particular its higher K-theory also vanishes.

It is proved that the internal hom of Ho(DGCat) constructed in (Toën 2004) is in fact the right derived functor of the internal hom of DGCat.

The (infinity,1)-categorical representability theorem of (Ben-Zvi-Francis-Nadler 2008) is extended to the non-smooth case.
