Power boundedness in Fourier and Fourier-Stieltjes algebra of an ultraspherical hypergroup

Reza Esmailvandi, Mehdi Nemati, N. Shravan kumar

Let $H$ be an ultraspherical hypergroup associated with a locally compact group $G$ and a spherical projector $\pi$ and let $A(H)$ and $B(H)$ denote the Fourier and Fourier-Stieltjes…
