Title: Complexes of stable infinity-categories
Abstract:
A complex of stable infinity-categories is a categorification of a chain 
complex, meaning
a sequence of stable infinity-categories together with a differential 
that squares to the
zero functor. We refer to such categorified complexes as categorical 
complexes. We give a
categorification of the totalization construction, which associates a 
categorical complex
with a categorical multi-complex. Special cases include the 
totalizations of commutative
squares or higher cubes of stable infinity categories. This can be used 
to construct
interesting examples of categorical complexes, for instance coming from 
normal crossing
divisors.
The study of categorical complexes can be seen as part of the 
conjectural/emerging subject
of categorified homological algebra. We will also indicate a partial 
formalisation of
this, based on the notion of a lax additive (infinity,2)-category, 
categorifying the
notion of an additive 1-category.
This talk is based on joint work with T. Dyckerhoff and T. Walde, see
https://arxiv.org/abs/2301.02606.
