We prove two results about mutation invariance of link homology theories: We show that Khovanov's universal sl(2) homology is invariant under mutation and that the reduced sl(n) homology defined by Khovanov and Rozansky is invariant under component-preserving positive mutation when n is odd. We also give a relationship between the Khovanov homology of a(More)
