Khovanov homology has been the subject of much study in knot theory and low dimensional topology since 2000. This work introduces a Khovanov Laplacian and a Khovanov Dirac to study knot and link diagrams. The harmonic spectrum of the Khovanov Laplacian or the Khovanov Dirac retains the topological invariants of Khovanov homology, while their non-harmonic spectra reveal additional information that is distinct from Khovanov homology.
自2000年以来,霍万诺夫同调一直是纽结理论和低维拓扑学中大量研究的主题。这项工作引入了一个霍万诺夫拉普拉斯算子和一个霍万诺夫狄拉克算子来研究纽结和链环图。霍万诺夫拉普拉斯算子或霍万诺夫狄拉克算子的调和谱保留了霍万诺夫同调的拓扑不变量,而它们的非调和谱则揭示了与霍万诺夫同调不同的额外信息。
