Examples of solvable and nonsolvable convolution equations in š’¦pā€², p ā‰„ 1

Abstract

For p [1,+) let 𝒦′p be the space of distributions on Rn not growing faster than some power of exp(|⋅|p), and let 𝒦be the space of distributions on Rn of finite order. For every p (1,+] the existence of convolutors f is proved such that f ∗𝒦p= 𝒦pbut f ∗𝒦s𝒦sfor every s < p. The main step in the proof is a construction of slowly decreasing entire functions which satisfy suitable estimates of Paley-Wiener type and which have countably many zeros of orders as high as possible.
