A spaceability result in the context of hypergroups


Abstract


In this paper, by an elementary constractive technique, it is shown that L^r(\mathbb{Z}_+)-\bigcup_{q<r}L^q(\mathbb{Z}_+) is non-empty, where \mathbb{Z}_+ is the dual of a compact countable hypergroup introduced by Dunkl and Ramirez. Also, we prove that for each r>1, L^r(\mathbb{Z}_+)-\bigcup_{q<r}L^q(\mathbb{Z}_+) is spaceable.
