On quasi-ideals and bi-ideals in ternary semirings

International Journal of Mathematics and Mathematical Sciences, 2005
We introduce the notions of quasi-ideal and bi-ideal in ternary semirings and study some properties of these two ideals. We also characterize regular ternary semiring in terms of these two subsystems of ternary semirings.

Pseudo‐Quantum Fractional Calculus and Existence of Solutions for Delay Pseudo‐Fractional Differential Equations in Generalized Banach Spaces

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper presents a new framework of pseudo‐q–fractional calculus in generalized Banach spaces by bringing together pseudo‐analysis, G–calculus, and quantum calculus. We introduce Liouville–Caputo and Riemann–Liouville pseudo‐q–fractional operators and outline their main properties. Then, by applying the Banach fixed point principle, we establish the

A Novel Approach to Decision‐Making Under Uncertainty Using Spherical Linear Diophantine Fuzzy Relations

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Fuzzy relations are more advanced than crisp binary relations, which are applicable in control systems in artificial intelligence. Our research study develops a fuzzy spherical linear Diophantine fuzzy (SLDFu) relation as a more advanced tool to handle uncertainty in decision‐making.

(m,n)-Semirings and a Generalized Fault-Tolerance Algebra of Systems

Journal of Applied Mathematics, 2013
We propose a new class of mathematical structures called (m,n)-semirings (which generalize the usual semirings) and describe their basic properties. We define partial ordering and generalize the concepts of congruence, homomorphism, and so forth, for (m ...

Brouwer’s Fixed Point Theorem and Open Mapping Theorem in Hemi‐Normed Spaces

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper aims for the further development of hemi‐normed spaces, which is a proper extension of normed spaces. In this regard, we establish some fundamental results of functional analysis, including Brouwer’s theorem and Schauder’s fixed point theorem for hemi‐normed spaces.

Derivations on the matrix semirings of max-plus algebra [PDF]

Journal of Mahani Mathematical Research
Let $(S,\oplus,\otimes)$ be a matrix semiring of max-plus algebra with the addition operation $\oplus$ and the multiplication operation $\otimes$, where the set \( S \) consists of matrices constructed from real numbers together with the element negative

On Weakly 1-Absorbing Primary Ideals of Commutative Semirings

Communications in Advanced Mathematical Sciences, 2022
Let $R$ be a commutative semiring with $ 1 \neq0$. In this paper, we study the concept of weakly 1-absorbing primary ideal which is a generalization of 1-absorbing ideal over commutative semirings . A proper ideal $I$ of a semiring $R$ is called a weakly

CNN‐Transformer Hybrid Network for Efficient Performance Prediction of Metasurfaces

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
This paper proposes an efficient metasurface simulation method leveraging deep neural networks to mitigate the time‐consuming and resource‐intensive nature inherent in traditional numerical simulation techniques. The proposed approach harnesses convolutional neural networks (CNNs) to extract metasurface features and employs a transformer network for ...

From Cultivation to Commerce: A Comprehensive Review of the Ecology, Chemistry, Production, Sustainability, and Market Prospects of an Ethiopian Herb Korarima (Aframomum corrorima)

Scientifica, Volume 2026, Issue 1, 2026.
Korarima (Aframomum corrorima) is a perennial aromatic herb native to Ethiopia, widely valued for its culinary, medicinal, and cultural importance. It naturally grows under shaded forest ecosystems; however, deforestation and habitat degradation have led to a significant decline in its wild populations.

∗-π-Reversible ∗-Semirings and Their Applications to Generalized Inverses

Journal of Mathematics
We introduce and study a new class of ∗-semirings which is called ∗-π-reversible ∗-semirings. A ∗-semiring R is said to be ∗-π-reversible if for any a,b∈R, ab=0 implies there exist two positive integers m and n such that bman∗=0.
