Speaker: Muriel Livernet (Paris Diderot)
Title: Model category structures for multicomplexes
Abstract:
Multicomplexes can be seen as deformations of chain complexes and we will present a nested family of weakequivalences 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 "selfcontained" and all notions will be motivated and defined.
