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 "…
-deformations of zigzag algebras via Ginzburg dg algebras
Junyang Liu, Zhengfang Wang
This note aims to give a short proof of the recent result due to Etgü-Lekili (2017) and Lekili-Ueda (2021): the zigzag algebra of any finite tree over a field of characteristic 0…
Partially wrapped Fukaya categories of orbifold surfaces
Severin Barmeier, Sibylle Schroll, Zhengfang Wang
We give a complete description of partially wrapped Fukaya categories of graded orbifold surfaces with stops. We show that a construction via global sections of a natural cosheaf o…
Discrete non-commutative hungry Toda lattice and its application in matrix computation
Zheng Wang, Shi-Hao Li, Kang-Ya Lu +1
In this paper, we plan to show an eigenvalue algorithm for block Hessenberg matrices by using the idea of non-commutative integrable systems and matrix-valued orthogonal polynomial…
