Model category structures on truncated multicomplexes for complex geometry

Algebraic Topology 2025-11-11 v2 Differential Geometry

Abstract

To a bicomplex one can associate two natural filtrations, the column and row filtrations, and then two associated spectral sequences. This can be generalized to NN-multicomplexes. We present a family of model category structures on the category of NN-multicomplexes where the weak equivalences are the morphisms inducing a quasi-isomorphism at a fixed page rr of the first spectral sequence and at a fixed page ss of the second spectral sequence. Such weak equivalences arise naturally in complex geometry. In particular, the model structures presented here establish a basis for studying homotopy types of almost and generalized complex manifolds.
