Study of (p, q)‐Symmetric Starlike Functions of Order η

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
In the field of geometric function theory, we use the (p, q)‐differential operator in the complex unit disk to describe a novel class Sp,q∗∗η of symmetrical starlike functions of order η. Several interesting properties of functions belonging to the class Sp,q∗∗η are examined, such as growth, distortion, and convolution characteristics.

Circular Chromatic Number of Signed Planar Graphs Without Cycles of Length 4 to 9

open access: yesMathematics
Given a signed graph (G,σ) and a positive real number r, if there exists a vertex mapping c:V(G)→[0,r) satisfying that for every positive edge wx, 1≤|c(w)−c(x)|≤r−1 and for every negative edge wx, |c(w)−c(x)|≤r2−1 or |c(w)−c(x)|≥r2+1, then (G,σ) admits a

Topological Aspects of Quadratic Graphs and M‐Polynomials Utilizing Classes of Finite Quasigroups

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
Material science, drug design and toxicology studies, which relate a molecule’s structure to its numerous properties and activities, are studied with the use of the topological index. Graphs with finite algebraic structure find extensive applications in fields such as mathematics, elliptic curve cryptography, physics, robotics and information theory ...

Finite Fuzzy Topologies on Boolean Algebras

open access: yesMathematics
We consider finite B-fuzzy topologies, that is, collections of mappings from a finite set to the Boolean algebra B, satisfying analogous conditions of classical topologies.
