Webexists a partition of unity {r-} with Idq,l --- E, then Eq. 9 holds for Y and consequently H12)(Y) = 0. Remark: The hypotheses do not imply H'2)(Ya) = 0 since Y,,, is not complete in general. The extension of these comments to L2-cohomology with coefficients is clear. To apply this, we recall the concept of distinguished cov-erings as in ref. 3.
