M-hazy semigroups
摘要
This paper focuses on the theory and properties of M-hazy semigroups based on M-hazy operations. First, leveraging M-hazy binary operation, we define M-hazy semigroups and introduce the concepts of commutative law, zero element and identity element. Subsequently, we define pointwise mappings from fuzzy points to fuzzy points and investigate the relationship between M-hazy pointwise mappings and classical mappings. Next, we introduces the notions of subsemigroups, ideals, homomorphisms, weak homomorphisms and isomorphisms for M-hazy semigroups. Building on these foundations, we prove the M-hazy faithful representation theorem for M-hazy semigroups. Finally, we define M-hazy rectangular bands and extend M-hazy pointwise mappings to two-dimensional spaces, thereby deriving fundamental properties of M-hazy rectangular bands.
