Sobolev mappings and the spectral sequence for Rumin's filtration on the de Rham complex

Differential Geometry 2022-05-10 v1

Abstract

We consider Rumin's filtration on the de Rham complex of a Carnot group. Although Pansu pullback by a Sobolev map is filtration preserving, it need not be a chain mapping. Nonetheless, we show that Pansu pullback induces a mapping of the associated spectral sequences. This gives an alternate interpretation of the Pullback Theorem from our previous paper.
