Symmetries of equivariant Khovanov-Rozansky homology
You Qi, Louis-Hadrien Robert, Joshua Sussan +1
We construct an -action on equivariant -link homologies. As a consequence we obtain an action of on these homologies as well as…
A braid group action on an -category for zigzag algebras
Benjamin Cooper, You Qi, Joshua Sussan
We construct differential graded enhancements of the zigzag algebras which were used by Khovanov, Seidel and Thomas to produce categorical braid group actions. These enhancements a…
Evaluating thin flat surfaces
Mikhail Khovanov, You Qi, Lev Rozansky
We consider recognizable evaluations for a suitable category of oriented two-dimensional cobordisms with corners between finite unions of intervals. We call such cobordisms thin fl…
A faithful braid group action on the stable category of tricomplexes
Mikhail Khovanov, You Qi
Bicomplexes of vector spaces frequently appear throughout algebra and geometry. In Section 2 we explain how to think about the arrows in the spectral sequence of a bicomplex via it…
