Title: Model category structures for multicomplexes

Abstract:

Multicomplexes can be seen as deformations of chain complexes and we will present a nested family of  weak-equivalences for multicomplexes, arising from the spectral sequence associated to multicomplexes. We will then show that there is a model category structure associated to this family of weak equivalences. The talk is "self-contained" and all notions will be motivated and defined.
