## Fuzzy $$H_v$$-groups.(English)Zbl 0935.20065

The fuzzy subhypergroups of a hypergroup and the fuzzy $$H_v$$-group of an $$H_v$$-group are defined and studied in this paper. The most interesting result is the main theorem concerning the fundamental group of the underlying $$H_v$$-group. This result proves, once more, how interesting the fundamental relations in the study of hyperstructures are.
