Cluster theory of topological Fukaya categories
M Christ - arXiv preprint arXiv:2209.06595, 2022 - arxiv.org
We study a class of generalized cluster categories arising from relative Ginzburg algebras of
triangulated marked surfaces without punctures. We show that these categories describe $1 …

Relative Calabi-Yau structures and perverse schobers on surfaces
M Christ - arXiv preprint arXiv:2311.16597, 2023 - arxiv.org
We discuss relative Calabi-Yau structures on functors between $ R $-linear stable $\infty $-
categories, with $ R $ any $\mathbb {E} _\infty $-ring spectrum, generalizing previous …

Perverse schobers, stability conditions and quadratic differentials II: relative graded Brauer graph algebras
We introduce a class of dg-algebras which generalize the classical Brauer graph algebras.
They are constructed from mixed-angulations of surfaces and often admit a (relative) Calabi …
