Description
In his thesis Stefano defines and studies coherent
cochain complexes in arbitrary stable ∞-categories, following Joyal. The main
result is that the ∞-category of coherent cochain complexes in a stable
∞-category C is equivalent to the ∞-category of complete filtered objects in C.
He then show how the Beilinson t-structure can be interpreted in light of such
equivalence, and analyze its behavior in the presence of symmetric monoidal
structures. He also examines the relationship between the notion of (higher)
Toda brackets and coherent cochain complexes.
Finally, he explains how every coherent cochain complex
gives rise to a spectral sequence and illustrates some examples.
