This paper reports on some applications of the theory of the local Fourier transform for hyperfunctions and the related duality theory for the space \(B/A\), where \(B\) is the space of germs of hyperfunctions at \(0 \in \mathbb{R}^{n}\) and \(A\) is the subspace of real-analytic functions in \(B\). Some results on the existence of boundary traces for one-sided solutions of linear partial pseudodifferential equations in the \(C^{\infty}\) case and the analytic case are given. Then, Hartogs type phenomena for hyperfunctions with holomorphic parameters are described. The proofs of these results are not given here.
