Tocalculate [Eââââ(f)](Ο)wetake intoaccountbothSTEP1andSTEP2. Thenweobtain

DeïŹnition 17. Let f âHom(Aâq,W) and Ο =X1â ...âXq+1 âAâq+1. We take into account Step 1,
Step2andStep3. Therefore,wedeïŹne the linearmap

We replace the category ofKValgebras and their two-sidedmodules by the category ofKV
algebroidsandtheirbi-modules. ThenwewinthegeometryversionofCH(D.
We use Lemma 2 for introducing a theory of KV homology of KV algebras and their
two-sidedmodules.
