Symmetries of colored Khovanov-Rozansky homology
Alexis Guérin, Felix Roz
We construct an action of the positive half of the Witt algebra on colored -Khovanov-Rozansky homology and prove that this action is compatible with the functorial…

An action of the Witt algebra on Khovanov-Rozansky homology
Alexis Guérin, Felix Roz
We construct an action of the positive part of the Witt algebra on Khovanov--Rozansky -link homology and show that link cobordisms induce equivariant maps between…
