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

Journal 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 ...

Computing Degree Based Topological Properties of Third Type of Hex-Derived Networks

Mathematics, 2019
In chemical graph theory, a topological index is a numerical representation of a chemical network, while a topological descriptor correlates certain physicochemical characteristics of underlying chemical compounds besides its chemical representation. The

Maximum augmented Zagreb index on polyomino chains

In this paper, we present a dynamic programming approach for identifying extremal polyomino chains with respect to degree-based topological indices. This approach provides an explicit recurrence and constructive algorithm that enables both the computation of an extremal polyomino chain in linear time with respect to its number of squares, and the ...

The Second Maximum Mostar Index of Unicyclic Graphs With Given Diameter

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Topological invariants are key tools for studying the physicochemical and thermodynamic properties of chemical compounds. Recently, a new bond‐additive distance‐based graph invariant called the Mostar index has been developed. It measures the importance of individual edges and the graph as a whole. It is denoted and defined as MoG=∑xy∈EGnxxy−nyxy. This

Human Evolution in Backwaters, Satellites, and Republics: How Political Change Impacts Paleoanthropology in a Shifting Landscape of Winners and Losers

American Journal of Biological Anthropology, Volume 188, Issue 4, December 2025.
ABSTRACT Objectives Paleoanthropology has been slow to adopt postcolonial frameworks to assess the validity of interpretations of human origins. This blind spot is made worse when we consider that postcolonial critique is often inappropriate for post‐communist spaces.
