A counterexample to the Jordan-Hölder property for polarizable semiorthogonal decompositions
Fabian Haiden, Dongjian Wu
We show that the Jordan-Hölder property fails for polarizable semiorthogonal decompositions -- those where every factor admits a Bridgeland stability condition. Counterexamples exi…
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…
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…
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…
Iterated logarithms and gradient flows
Fabian Haiden, Ludmil Katzarkov, Maxim Kontsevich +1
We consider applications of the theory of balanced weight filtrations and iterated logarithms, initiated in arXiv:1706.01073, to PDEs. The main result is a complete description of…
