Abstract
In their recent preprint, Baldwin, Ozsv\'{a}th and Szab\'{o} defined a twisted version (with coefficients in a Novikov ring) of a spectral sequence, previously defined by Ozsv\'{a}th and Szab\'{o}, from Khovanov homology to Heegaard-Floer homology of the branched double cover along a link. In their preprint, they give a combinatorial interpretation of the -term of their spectral sequence. The main purpose of the present paper is to prove directly that this -term is a link invariant. We also give some concrete examples of computation of this invariant.
