Matrix factorizations and double line in ${\mathfrak{sl}}_n$ quantum link invariant

Abstract

This article gives matrix factorizations for the trivalent diagrams and double line appearing in ${\mathfrak{sl}}_n$ quantum link invariant. These matrix factorizations reconstruct Khovanov-Rozansky homology. And we show that the Euler characteristic of the matrix factorization for a double loop equals the quantum dimension of the representation ${\wedge }^{2}V$ of $U_q({\mathfrak{sl}}_n)$ in Section \ref{sec3.3}.
