A faithful braid group action on the stable category of tricomplexes
arXiv:1911.02503 · doi:10.3842/SIGMA.2020.019
Abstract
Bicomplexes of vector spaces frequently appear throughout algebra and geometry. In Section 2 we explain how to think about the arrows in the spectral sequence of a bicomplex via its indecomposable summands. Polycomplexes seem to be much more rare. In Section 3 of this paper we rethink a well-known faithful categorical braid group action via an action on the stable category of tricomplexes.
