On the Left and Right Almost Hyperideals of LA-Semihypergroups

Abstract

In this paper, we define left almost hyperideals, right almost hyperideals, almost hyperideals, and minimal almost hyperideals. We demonstrate that the intersection of almost hyperideals is not required to be an almost hyperideal, but the union of almost hyperideals is an almost hyperideal, which is completely different from the classical algebraic concept of the ideal theory.

Hypergroupoids as Tools for Studying Blood Group Genetics

“…For example, a man with type AB blood cannot father a child with type O blood, as is evident in Table 8, because he would pass on either the A or B allele to all of his offspring [16]. The ABO blood groups cannot be used to confirm whether a man is indeed a child's father.…”

Applications of Bipolar Fuzzy Almost Ideals in Semigroups

“…al [3] studied the almost bi-quasi-interior ideal and fuzzy almost bi-quasi-interior ideal in semigroups. Moreover, related research to various types of almost ideals has been studied in other algebraic structures (see, e.g., [9,11,12,[14][15][16][17]). Recently N. Sarasit et al [13] studied almost ternary subsemirings.…”

Characterization of almost filters and their fuzzifications of semigroups

“…Research on various types of almost ideals and fuzzy almost ideals has also been conducted in specialized areas such as Γ -semigroups [7,18,19], ordered semigroups [20,23], ternary semigroups [22], semihypergroups [6,13,15,21,24], and LA-semihypergroups [14], including studies on bipolar fuzzy sets [9,10].…”
