Abstract.

In this paper we study the Hankel transformation and convolution on certain spaces \({\cal G}_{e}\) of entire functions and its dual \({\cal G}_{e}{\prime}\) that is a space of hyperfunctions and contains the (even)-Schwartz space S e ′. We prove that the Hankel transform is an automorphism of \({\cal G}_{e}{\prime}\). Also the Hankel convolutors of \({\cal G}_{e}{\prime}\) are investigated.
