Fukaya categories of orbifold surfaces in representation theory
Severin Barmeier, Zhengfang Wang
We give an introduction to partially wrapped Fukaya categories of surfaces with orbifold singularities. Dissecting an orbifold surface into polygons, certain dissection…

Deformations of partially wrapped Fukaya categories of surfaces
Severin Barmeier, Sibylle Schroll, Zhengfang Wang
We give a complete description of the A deformation theory of partially wrapped Fukaya categories of graded surfaces. We show that any abstract A deformation is "…

A deformations of extended Khovanov arc algebras and Stroppel's conjecture
Severin Barmeier, Zhengfang Wang
Extended Khovanov arc algebras are graded associative algebras which naturally appear in a variety of contexts, from knot and link homology, low-dimensional topolo…
