Analytic Dirac approximation for real linear algebraic groups

For a real linear algebraic group G let A(G) be the algebra of analytic vectors for the left regular representation of G on the space of superexponentially decreasing functions. We present an explicit Dirac sequence in A(G). Since A(G) acts on E for every Frechet-representation (π,E) of moderate growth, this yields an elementary proof of a result of Nelson that the space of analytic vectors is dense in E.
