We give some examples of abelian categories A for which the derived category D(A) is not left-complete. Perhaps the most natural of these is where A is the category of representations of the additive group G_a over a field k of characteristic p>0.

  1. Deformations of triangulated categories with t-structures via derived injectives

    math.CT 2024-11 conditional novelty 7.0 of 10

    Bounded t-deformations of a bounded t-dg-category are equivalent to dg-deformations of its category of derived injectives, and HH^n classifies them for n at least 2.
