Iterates of systems of operators in spaces of $\omega$-ultradifferentiable functions

Chiara Boiti, Rachid Chaïli, Tayeb Mahrouz

Given two systems $P=(P_j(D){)}_{j=1}^N$ and $Q=(Q_j(D){)}_{j=1}^M$ of linear partial differential operators with constant coefficients, we consider the spaces ${\mathcal{E}}_{\omega }^P$ and $…
