 With minor modifications, one can also define complex-valued distributions, and one can replace R"n" by any (paracompact) smooth manifold.For any formula_28 let formula_29 denote the vector space of all "k"-times continuously differentiable complex-valued functions on formula_30.Recall that the support of a function "f", denoted by formula_31, is the closure in formula_32 of the set formula_33.
