A non-semisimple non-invertible symmetry

C Delcamp, E Heng, M Yu - arXiv preprint arXiv:2412.19635, 2024 - arxiv.org
We investigate the action of a non-semisimple, non-invertible symmetry on spin chains,
whose topological defects encode the category of modules over the Taft algebra of …

Stability conditions and Artin--Tits groups

E Heng, AM Licata - arXiv preprint arXiv:2412.15919, 2024 - arxiv.org
We describe spaces of Bridgeland stability conditions on certain triangulated categories
associated to Coxeter systems. These categories are defined algebraically using the …
