Gluing abelian categories and stability conditions
Charalampos Evangelatos, Fabian Haiden
We study the support property for stability conditions obtained by gluing along semiorthogonal decompositions. Our main tool is a new gluing construction for abelian categories alo…
Perverse schobers, stability conditions and quadratic differentials I
Merlin Christ, Fabian Haiden, Yu Qiu
We develop a unified approach for identifying spaces of stability conditions of triangulated categories arising from weighted marked surfaces with moduli spaces of quadratic differ…
Perverse schobers, stability conditions and quadratic differentials II: relative graded Brauer graph algebras
Merlin Christ, Fabian Haiden, Yu Qiu
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) Calab…
Braid group actions on branched coverings and full exceptional sequences
Wen Chang, Fabian Haiden, Sibylle Schroll
We relate full exceptional sequences in Fukaya categories of surfaces or equivalently in derived categories of graded gentle algebras to branched coverings over the disk, building…
Counting in Calabi--Yau categories, with applications to Hall algebras and knot polynomials
Mikhail Gorsky, Fabian Haiden
We show that homotopy cardinality -- a priori ill-defined for many dg-categories, including all periodic ones -- has a reasonable definition for even-dimensional Calabi--Yau (evenC…
The stability manifold of
Fabian Haiden, Benjamin Sung
We determine a full component of the space of stability conditions on where is an elliptic curve without complex multiplication. The component has complex dimension…
