• Inf-hesitant fuzzy subsemigroup
• inf-hesitant fuzzy left (right) ideal
• inf-hesitant fuzzy quasi-ideal

The notions of Inf-hesitant fuzzy subsemigroups, Inf-hesitant fuzzy left (right) ideals and Inf-hesitant fuzzy quasi-ideals in semigroups are introduced, and their relations and properties are investigated. Characterizations of an Inf-hesitant fuzzy subsemigroup and an Inf-hesitant fuzzy left (right) ideal are discussed. Characterizations of a quasi-ideal and a regular semigroup are considered.
