Positselski duality in $\infty$ -categories

Torgeir AambÃ¸

We introduce the notion of a contramodule over a cocommutative coalgebra in a presentably symmetric monoidal $\infty$ -category $C$ , and prove a symmetric monoidal $\infty…

Classification of localizing subcategories along t-structures

Torgeir AambÃ¸

We study the interplay between localizing subcategories in a stable $\infty$ -category $C$ with $t$ -structure $(C_{\geq 0}, C_{\leq 0})$ , the prestable…

Algebraicity in monochromatic homotopy theory

Torgeir AambÃ¸

Using Patchkoria--PstrÄ gowski's version of Franke's algebraicity theorem, we prove that the category of $K_{p} (n)$ -local spectra is exotically equivalent to the category of derived…
