Abstract
We furnish any category of a universal (co)homology theory. Universal (co)homologies and universal relative (co)homologies are obtained by showing representability of certain functors and take values in -linear abelian categories of motivic nature, where is any commutative unitary ring. Universal homology theory on the one point category yields "hieratic" -modules, i.e. the indization of Freyd's free abelian category on . Grothendieck -functors and satellite functors are recovered as certain additive relative homologies on an abelian category for which we also show the existence of universal ones.
