Abstract: 
I will outline a technique, introduced by me and Ben Elias, for computing the HOMFLY version of Khovanov-Rozansky homology.  I will show how this technique gives a simple recursion which computes the homology of positive torus links (recently accomplished in special cases by me, and in generality by Anton Mellit).  Time permitting, I would like to use these computations for 3-strand braids to illustrate a connection with recent conjectures of Gorsky-Negut-Rasmussen.
