| Sep 20 at 13:03 | comment | added | R. van Dobben de Bruyn | One of the main reasons to work with higher enhancements of triangulated categories (such as differential graded categories, model categories, or any flavour of $\infty$-categories) is that 'basic' category theory constructions behave better. Taking Ind-categories is one example of this (others include taking $\operatorname{Fun}(\mathcal I,\mathcal K)$ from some small category $\mathcal I$). The usual derived category is a homotopy category of one of these enhancements, and taking homotopy category does not commute with most basic operations in (higher) category theory. | |
