(c.1): Wereplace theKVB byA. Thenweobtain the exact sequences
→Hq−1KVres(A,V)→Hqe(A,V)→HqKV(A,V)→HqKVres(A,V)→
→Hq−1τres(A,V)→Hqe(A,V)→Hqτ(A,V)→Hqτres(A,V)→
(c.2): The KV cohomology difers from the total cohomology. Loosely speaking their intersecttion is the
equivariant cohomology H∗e(B,V) their difference is the residual cohomology. The domain of their
efficiencyaredifferentaswell.Hereare two illustrations.
Example1.
In the introductionwehavestatedaconjectureofM.Gerstenhaber,namelyEveryRestrictedTheory
ofDeformationGenerates ItsProperTheoryofCohomology.
From the viewpoint of this conjecture, the KV cohomology is the completion a long
history [2,9,28]. BesidesKoszul andNijenhuis, otherpioneering authors areVinberg, Richardson,
Gerstenhaber,Matsushima,Vey.
Thechallengewas thesearch fora theoryofcohomologywhichmightbegeneratedbythe theory
ofdeformationof locallyflatmanifolds [8]. Theexpectedtheory is thenowknownKVtheoryofKV
cohomolgy[9].
Example2.
The total cohomology is close toboth thepioneeringNijenhuiswork [28,36]. In [29]wehave
constructedaspectral sequencewhichrelates to [28,36].
From another viewpoint, the total KV cohomology is useful for exploring the relationships
between the informationgeometryand the theoryofRiemannian foliations. Thispurposewill be
addressed in thenextsections.
3.3. TheTheoryofKVCohomology—Version theAnomalyFunctions
This subsection is devoted to use the KV anomaly functions for introducing the theory of
cohomologyofKValgebroidsandtheirmodules.
This viewpoint leads to anunifying framework for introducing the theoryof cohomologyof

Example 3. The theoryof cohomologyofLeibniz algebras is basedon the Jacobi anomaly function
aswell.
