A mixed invariant of non-orientable surfaces in equivariant Khovanov homology
Robert Lipshitz, Sucharit Sarkar
We construct a mixed invariant of non-orientable surfaces from the Lee and Bar-Natan deformations of Khovanov homology and use it to distinguish pairs of surfaces bounded by the sa…

Robert Lipshitz, Peter Ozsváth, Dylan Thurston
We describe a weighted -algebra associated to the torus. We give a combinatorial construction of this algebra, and an abstract characterization. The abstract characteriza…

Homotopy functoriality for Khovanov spectra
Tyler Lawson, Robert Lipshitz, Sucharit Sarkar
We prove that the Khovanov spectra associated to links and tangles are functorial up to homotopy and sign.
