abstract

We study the problem of when triangulated categories admit unique infinity-categorical enhancements. Our results use Lurie's theory of prestable infinity-categories to give conceptual proofs of, and in many cases strengthen, previous work on the subject by Lunts--Orlov and Canonaco--Stellari. We also give a wide range of examples involving quasi-coherent sheaves, categories of almost modules, and local cohomology to illustrate the theory of prestable infinity-categories. Finally, we propose a theory of stable $n$-categories which would interpolate between triangulated categories and stable infinity-categories.

  1. Strong uniqueness of enhancements for the dual numbers: a case study

    math.AG 2025-05 conditional novelty 7.0 of 10

    The paper proves that the derived categories of modules over the dual numbers, in the bounded, bounded below, and strictly bounded ranges, and all derived categories of hereditary abelian categories, have strongly uni...

  2. The derived $\infty$-category of Frobenius modules

    math.AG 2025-10 conditional novelty 6.0 of 10

    For any quasi-compact F_p-scheme with affine diagonal, the derived ∞-category of Frobenius modules is t-exactly equivalent to Frobenius modules on the derived ∞-category, and both satisfy Zariski descent.
