Monoidal structures arising from -algebras with applications to Hopf algebras
Gongxiang Liu, Zhengfang Wang, Mengdie Zhang
We give an explicit construction of monoidal structures on derived categories of right -modules over an -algebra equipped with a -structure. Given…
Hochschild Cohomology of the Symmetric Square of an Annulus with Stops
Xingyuan Lu, Zhengfang Wang
We compute the Hochschild cohomology of the partially wrapped Fukaya category of the symmetric square of an annulus with stops. Using an explicit generating set in this category, w…
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…
The second Hochschild cohomology and deformations of Brauer graph algebras
Yuming Liu, Zhengfang Wang, Bohan Xing
In this paper, we give an explicit description about the second Hochschild cohomology groups of bipartite Brauer graph algebras with trivial grading. Based on this, we provide geom…
-structures on the additive decomposition of the Tate-Hochschild cohomology of a finite group algebra
Xiuli Bian, Longfei Li, Yuming Liu +3
Firstly, for a finite group algebra, we provide a computational framework for the Tate-Hochschild cochain complex in terms of the additive decomposition, by decompo…
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 "…
