| Outline of Final Research Achievements |
On kernel theorems in hyperfunctions, we got some partial results for the purpose of the study on locally convex cases. We established the division by differential operators of infinite order with parameters and its variant related to BMT classes, and got the support properties and the analytic singular support properties for integral transformations. We also worked on bounded hyperfunctions at infinity, and gave a notion of fading memory for operators with infinite delay. Moreover we got results on boundary value representations, dualities, and periodic equations.
