arXiv preprint math/0401268, 2004•arxiv.orgFor each positive integer n the HOMFLY polynomial of links specializes to a one-variable
polynomial that can be recovered from the representation theory of quantum sl (n). For each
such n we build a doubly-graded homology theory of links with this polynomial as the Euler
characteristic. The core of our construction utilizes the theory of matrix factorizations, which
provide a linear algebra description of maximal Cohen-Macaulay modules on isolated
hypersurface singularities.
