Amenable hypergroups

open access: yesIllinois Journal of Mathematics, 1992
A hypergroup is a locally compact space \(K\) whose finite Borel measures have a convolution (*) structure preserving positivity and so that \(\mu\to\int_ Kd\mu\) is a multiplicative functional. One can define left translation by \(\delta_ x\) (unit point mass at \(x \in K\)) for functions in \(L^ \infty(K)\).
