Remark 51.5.6. Let A be a Noetherian ring. Let T \subset \mathop{\mathrm{Spec}}(A) be a subset stable under specialization. The upshot of the discussion above is that R\Gamma _ T : D^+(A) \to D_ T^+(A) is the right adjoint to the inclusion functor D_ T^+(A) \to D^+(A). If \dim (A) < \infty , then R\Gamma _ T : D(A) \to D_ T(A) is the right adjoint to the inclusion functor D_ T(A) \to D(A). In both cases we have

H^ i_ T(K) = H^ i(R\Gamma _ T(K)) = R^ iH^0_ T(K) = \mathop{\mathrm{colim}}\nolimits _{Z \subset T\text{ closed}} H^ i_ Z(K)

This follows by combining Lemmas 51.5.2, 51.5.3, 51.5.4, and 51.5.5.
