“…For the case of general compactly supported v, we can use the partition of unity to reduce to the case above; we omit the details. Thus, if additionally (M, h) is a complete manifold (so that the Andreotti-Vesentini density lemma applies) and u ∈ dom(D * ), then we have a local expression for D * u as follows (see, e.g., [6, (6.20)] or [2]):…”
