Entropy2016,18, 433 AvectorbundleV is a two-sidedKVmoduleofaKoszul-Vinbergalgebroid(E,b) if it satisfies the identities L(s, f,v)=0, KV(s,s∗,v)=0, KV(s,v,s∗)=0. Warning. ConsideravectorV spaceas the trivialvectorbundle V×O→0. Thenweget Γ(V×0)=V. Therefore analgebra is ananchoredalgebroidover apoint; its anchormapof is the zeromap. Therefore, theLeibnizanomalyofanalgebra isnothingbut thebilinearityof themultiplication. So thenotionofKValgebra andKVmodule is clear. 3.TheTheoryofCohomologyofKVAlgebroidsandTheirModules Thissection isdevotedto thecohomologyofKValgebroidsandKVmodulesofKValgebroids.
