A Re‐Examination of Foundational Elements of Cosmology
Fortschritte der Physik, Volume 74, Issue 3, March 2026.ABSTRACT This paper undertakes a conceptual re‐examination of several foundational elements of cosmology through the lens of spacetime symmetries. A new derivation of the Friedmann–Lemaître–Robertson–Walker metric is obtained by a careful conceptual examination of rotations and translations on generic manifolds, followed by solving the rotational and ...

Leibniz algebras of dimension 3 over finite fields
Доповiдi Нацiональної академiї наук УкраїниThe first thing in the study of all types of algebras is the description of algebras having small dimensions. Unlike the simpler cases of 1- and 2-dimensional Leibniz algebras, the structure of 3-dimensional Leibniz algebras is more complicated.

A Wave Tank Study on Turbulent Transport of a Passive Tracer Above Gravelly Sand Beds
Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract Exchange processes at the seabed interface have a non‐negligible impact on biogeochemical processes of the sea. Acknowledging this impact on the input of nutrients from the seabed into the water column further entails properly assessing the transport and mixing of these nutrients within the water column.

Calculations on Lie Algebra of the Group of Affine Symplectomorphisms
Advances in Mathematical Physics, 2017 We find the image of the affine symplectic Lie algebra gn from the Leibniz homology HL⁎(gn) to the Lie algebra homology H⁎Lie(gn). The result shows that the image is the exterior algebra ∧⁎(wn) generated by the forms wn=∑i=1n(∂/∂xi∧∂/∂yi).

Leibniz algebras constructed by Witt algebras [PDF]
Linear and Multilinear Algebra, 2018 We describe infinite-dimensional Leibniz algebras whose associated Lie algebra is the Witt algebra and we prove the triviality of low-dimensional Leibniz cohomology groups of the Witt algebra with the coefficients in itself.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.Abstract Column‐integrated moist static energy (MSE) budgets underpin theories of tropical convection and circulation, yet in reanalyses and climate models the budget rarely closes; residuals routinely match the leading terms and mask physical insights.

Entropy as a Metric Generator of Dissipation in Complete Metriplectic Systems
Entropy, 2016 This lecture is a short review on the role entropy plays in those classical dissipative systems whose equations of motion may be expressed via a Leibniz Bracket Algebra (LBA). This means that the time derivative of any physical observable f of the system

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract Number theory for positive characteristic contains analogues of the special values that were introduced by Carlitz; these include the Carlitz gamma values and Carlitz zeta values. These values were further developed to the arithmetic gamma values and multiple zeta values by Goss and Thakur, respectively.
