A differential operator representation of continuous homomorphisms between the spaces of entire functions of given proximate orders
Takashi Aoki, Ryuichi Ishimura, Yasunori Okada
In this paper, we consider the locally convex spaces of entire functions with growth given by proximate orders, and study the representation as a differential operator of a continu…

Generalized spherical mean value operators on Euclidean space
Yasunori Okada, Hideshi Yamane
We consider the Neumann version of the spherical mean value operator and its variants in the space of smooth functions, distributions and compactly supported ones. Surjectivity and…
