Abstract

Given a pointed 4-ended tangle TD3T \subset D^3, there are two Khovanov theoretic tangle invariants, \unicode10441(T)\unicode{1044}_1(T) from [arXiv:1910.1458] and LTL_T from [arXiv:1808.06957], which are twisted complexes over the Fukaya category of the boundary 4-punctured sphere (S2,4pt)=(D3,T)(S^2,4\text{pt})=\partial (D^3, T). We prove that these two invariants are the same.
