A Standard Generator/Parity Check Matrix for Codes from the Cayley Tables Due to the Non-associative (123)-Avoiding Patterns of AUNU Numbers [PDF]

open access: yesUniversal Journal of Applied Mathematics, 2016
In this paper, we aim at utilizing the Cayley tables demonstrated by the Authors[1] in the construction of a Generator/Parity check Matrix in standard form for a Code say C Our goal is achieved first by converting the Cayley tables in [1] using Mod2 arithmetic into a Matrix with entries from the binary field.

Random Lie bracket on sl2(Fp)

open access: yesRandom Structures &Algorithms, Volume 68, Issue 1, January 2026.
ABSTRACT We study a random walk on the Lie algebra sl2(Fp)$$ {\mathfrak{sl}}_2\left({\mathbf{F}}_p\right) $$ where new elements are produced by randomly applying adjoint operators of two generators. Focusing on the generic case where the generators are selected at random, we analyze the limiting distribution of the random walk and the speed at which it

Partial Observability of Implied Volatility Matrices: Identification and Covolatilities Filtering

open access: yesMathematical Finance, Volume 36, Issue 1, Page 48-66, January 2026.
ABSTRACT Whereas data on implied volatilities are available for a large number of assets, this is less frequently the case of implied covolatilities. We introduce a new approach based on static and dynamic Wishart models to solve this problem of missing data.

Textural and geochemical diversity of impact melt rock clasts in Apollo 16 sample 67015: Implications for the provenance of impact ejecta in the lunar highlands

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 1, Page 39-63, January 2026.
Abstract Apollo sample 67015 has been classified as a fragmental breccia comprised of highlands‐type clasts and is proposed to be the most complex Apollo 16 sample. 67015 is dominated by impact melt rock clasts that display a variety of textures, which have been previously interpreted to be indicative of multiple impact events.

The founding of the Journal of the London Mathematical Society and its first volume

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract That the Journal of the London Mathematical Society came into existence in 1926 can be ascribed to the efforts of one man: G.H. Hardy. As one of the two Secretaries of the Society, Hardy was aware of the increasing demand for publication space in the Society's Proceedings, and the need for an outlet for shorter papers.

Combination theorems for Wise's power alternative

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We show that Wise's power alternative is stable under certain group constructions, use this to prove the power alternative for new classes of groups and recover known results from a unified perspective. For groups acting on trees, we introduce a dynamical condition that allows us to deduce the power alternative for the group from the power ...

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 ...

A Discrete Mechanics Approach to the Cosserat Rod Theory—Part II: Geometric Insights About Static Equilibria on Vertex and Staggered Grids

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 23, 15 December 2025.
ABSTRACT We apply the discrete mechanics approach to the discretisation of geometrically exact Cosserat rods. We consider discrete Cosserat rods defined on a vertex (or nodal) grid, as well as on a staggered grid, and provide a review and update of the results already obtained in Part I for the nodal model variant and, for the first time, present a ...

(Random) Trees of Intermediate Volume Growth

open access: yesRandom Structures &Algorithms, Volume 67, Issue 4, December 2025.
ABSTRACT For every function g:ℝ≥0→ℝ≥0$$ g:{\mathbb{R}}_{\ge 0}\to {\mathbb{R}}_{\ge 0} $$ that grows at least linearly and at most exponentially, if it is sufficiently well‐behaved, we can construct a tree T$$ T $$ of uniform volume growth g$$ g $$, or more precisely, C1·g(r/4)≤|BG(v,r)|≤C2·g(4r),for allr≥0andv∈V(T),$$ {C}_1\cdotp g\left(r/4\right)\le \

A Review on Kinematically Redundant Parallel Mechanisms With Configurable Platforms

open access: yesSmartBot, Volume 1, Issue 4, December 2025.
This review systematically combs the development context and technical system of Parallel Mechanisms with Configurable Platforms (PMCPs). Furthermore, through the progressive logic of classification, analysis and application, the paper reveals how “kinematic redundancy” and “configurable platform” break through the rigid limitations of traditional ...
