On the comaximal graph of a ring

AKCE International Journal of Graphs and Combinatorics
In this paper, we prove that the study of the comaximal graph of a finite commutative ring with identity is the same as the study of the zero-divisor graph of the specially constructed lattice.

Dual spaces of geodesic currents

Journal of Topology, Volume 18, Issue 4, December 2025.
Abstract Every geodesic current on a hyperbolic surface has an associated dual space. If the current is a lamination, this dual embeds isometrically into a real tree. We show that, in general, the dual space is a Gromov hyperbolic metric tree‐graded space, and express its Gromov hyperbolicity constant in terms of the geodesic current.

Robust Bounds on the Eigenvalues of Linear Systems With Delays and Their Applications in Stability Analysis

International Journal of Robust and Nonlinear Control, Volume 35, Issue 16, Page 6636-6651, 10 November 2025.
ABSTRACT We review some known bounds on the eigenvalues of a matrix and use similar techniques to derive bounds for the class of nonlinear eigenproblems and, as a special case, the eigenvalues for LTI systems with delays. We present two classes of results.

Commuting Pairs in Quasigroups

Journal of Combinatorial Designs, Volume 33, Issue 11, Page 418-427, November 2025.
ABSTRACT A quasigroup is a pair ( Q , ∗ ), where Q is a nonempty set and ∗ is a binary operation on Q such that for every ( a , b ) ∈ Q 2, there exists a unique ( x , y ) ∈ Q 2 such that a ∗ x = b = y ∗ a. Let ( Q , ∗ ) be a quasigroup. A pair ( x , y ) ∈ Q 2 is a commuting pair of ( Q , ∗ ) if x ∗ y = y ∗ x.

ON (L,M)-FUZZY TOPOGENOUS SPACES

Journal of New Theory, 2015
In this paper, we introduce the concept of an (L, M )-fuzzy topogenous space, whereL, M are strictly two sided commutative quantales lattices. Basic properties of (L, M )-fuzzy topogenous spaces are studied, (L, M )-fuzzy topological spaces, (L, M ...

Meta‐Metamodelling of Engineering Systems by Help of Abstract Mathematics

Mathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 14815-14827, 15 November 2025.
ABSTRACT The growing trend of automation in engineering significantly increases the complexity of engineering systems and necessitates a deeper understanding of the coupling of physical and cyber components interacting within the systems. A typical example of such a highly coupled system is an autonomous construction site, where robotic systems aim to ...
