KNOT HOMOLOGY OF (3, m) TORUS KNOTS

We give a direct computation of the Khovanov knot homology of the (3, m) torus knots/links. Our computation yields complete results with Z[1/2] coefficients, though we leave a slight ambiguity concerning 2-torsion when integer coefficients are used. Our computation uses only the basic long exact sequence in knot homology and Rasmussen's result on the triviality of the embedded surface invariant.
