Abstract:

EL-hypergroups were defined by Chvalina ۱۹۹۵. Tillnow, no exact statistics of EL-hypergroups have been done.\\ Moreover, there is no classification of EL-hypergroups and EL^۲-hypergroups even over small sets.In this paper, we classify all EL-(semi)hypergroups over sets withtwo elements obtained from quasi ordered semigroups. Also, we characterize all quasi ordered H_v-group and then we enumerate the number of EL^۲-H_v-hypergroups and EL^۲-hypergroups of order ۲.
