【 摘 要 】
In this paper we present a fixed point property for amenablehypergroups which is analogous to Rickert's fixed point theoremfor semigroups. It equates the existence of a left invariant mean on the space of weakly right uniformly continuous functionsto the existence of a fixed point for any action of the hypergroup. Using this fixed point property, a certain class of hypergroupsare shown to have a left Haar measure.
