Abstract
We show that Rasmussen's invariant of knots, which is derived from Lee's variant of Khovanov homology, is equal to an analogous invariant derived from certain other filtered link homologies.

There are two errors in the proof of Proposition 3.2. in this paper. These are indicated in an erratum added at the beginning. As a consequence the proof of Proposition 3.2 no longer holds and the proof of Theorem 4.2, which relies on it, is no longer valid
