Relations between a bordered GE-algebra and a bounded Hilbert algebra are stated, and the conditions under which every bordered GE-algebra (resp., bounded Hilbert algebra) can be a bounded Hilbert algebra (resp., bordered GE-algebra) are found.

An element-wise characterization is derived for the smallest GE-filter containing a given set. It is proved that the set of all GE-filters of a transitive GE-algebra forms a complete distributive lattice. Four different versions of a prime filter theorem are generalized in transitive GE-algebras. A necessary and sufficient condition is derived for a proper filter of a commutative GE-algebra to become a prime filter.https://jas.shahroodut.ac.ir/article_2835_300aa20d6cfe0944e1e6b3a24cfd13f5.pdfShahrood University of TechnologyJournal of Algebraic Systems2345-512812120240901THE UNIT GRAPH OF A COMMUTATIVE SEMIRING7989283610.22044/jas.2022.11957.1612ENLaithunBoroDepartment of Mathematics, North-Eastern Hill University P.O.

A proper hyperideal $P$ of $R$ is an $I-$prime hyperideal if for $a, b \in R$ with $ab \subseteq P-IP$ implies $a \in P$ or $b \in P$. We provide some characterizations of $I-$prime hyperideals. Also we conceptualize and study the notions $2-$absorbing $I-$prime and $n-$absorbing $I-$prime hyperideals into multiplicative hyperrings as generalizations of prime ideals. A proper hyperideal $P$ of a hyperring $R$ is an $n-$absorbing $I-$prime hyperideal if for $x_1, \cdots,x_{n+1} \in R$ such that $x_1 \cdots x_{n+1} \subseteq P-IP$, then $x_1 \cdots x_{i-1} x_{i+1} \cdots x_{n+1} \subseteq P$ for some $i \in \{1, \cdots ,n+1\}$. We study some properties of such generalizations. We prove that if $P$ is an $I-$prime hyperideal of a hyperring $R$, then each of $\frac{P}{J}$, $S^{-1} P$, $f(P)$, $f^{-1}(P)$, $\sqrt{P}$ and $P[x]$ are $I-$prime hyperideals under suitable conditions and suitable hyperideal $I$, where $J$ is a hyperideal contains in $P$. Also, we characterize $I-$prime hyperideals in the decomposite hyperrings. Moreover, we show that the hyperring with finite number of maximal hyperideals in which every proper hyperideal is $n-$absorbing $I-$prime is a finite product of hyperfields.https://jas.shahroodut.ac.ir/article_2840_8f4d1faed84b37d6d78b9129a5bd11af.pdfShahrood University of TechnologyJournal of Algebraic Systems2345-512812120240901ON INVERSE LIMIT OF A PROJECTIVE SYSTEM OF BL-ALGEBRAS123133284110.22044/jas.2022.12222.1643ENRezaTayebi KhoramiDepartment of Mathematics, Ahvaz Branch, Islamic Azad University, Ahvaz, Iran.0000-0003-3291-722XJournal Article20220819In this paper, the inverse limits of a projective system of basic logic algebras (BL-algebras) are introduced, and their basic properties are studied.
