On the range of convolution operators on non-quasianalytic ultradifferentiable functions. (English) Zbl 0918.46039
For a given weight function $$\omega: [0,\infty)\to [0,\infty)$$ and an open set $$\Omega\subseteq \mathbb{R}^n$$, the authors denote by $${\mathcal E}_{(\omega)}(\Omega)$$ the non-quasianalytic class of Beurling type on $$\Omega$$. They investigate conditions guaranteeing the surjectivity of the convolution operator $$T_\mu:{\mathcal E}_{(\omega)}(\Omega_1)\to {\mathcal E}_{(\omega)}(\Omega_2)$$ for the given $$\mu\in{\mathcal E}_{(\omega)}'(\mathbb{R}^n)$$. Analogous results are obtained also for ultradistributions of Roumieu type $${\mathcal D}_{(\omega)}'(\Omega)$$.
