Abstract
We characterize the partial differential operators $P(D)$ admitting a continuous linear right inverse in the space of Fourier hyperfunctions by means of a dual $( \overline{\Omega})$-type estimate valid for the bounded holomorphic functions on the characteristic variety $V_P$ near $\mathbb R^d$. The estimate can be transferred to plurisubharmonic functions and is equivalent to a uniform (local) Phragmén–Lindelöf-type condition.
