Distributions with Compact Support Frechet space and Definition For open is the space of [T] Proposition 21.1 A linear function is in is a distributions with compact support in with order where

Fourier-Laplace-Borel Transform Definition For [H] Thm7.3.1 Paley-Wiener-Schwartz is compact and convex and let If is entire, then of orderand with Iff where

Convergence to Distributions are complex measures distribution with compact support. Theorem 2. If converges to a and such that total variation Proof First proved in [DD] using the Paley-Wiener-Schwartz Theorem. [L] gave another proof, based on the Taylor expansion, and used it to generalize the theorem to Lie groups. and then

Convergence to Analytic Functionals are complex measures analytic functional Theorem 3. If converges to an and such that total variation Proof First proved in [U] using the Paley-Wiener-Ehrenpreis Theorem. We gave another proof, based on the Taylor expansion, and used it to generalize the theorem to Lie groups. and then
