On a class of Lie algebras [PDF]
Proceedings of the American Mathematical Society, 1965 In 1958, Block constructed a new class e3 of simple Lie algebras, O(G, 8, f) [1]. Here 5 is the direct sum of a finite number of finite elementary p-groups, Go, , * * j Gn, p>2 and a=61+ * * * +& where bi is a nonzero element of Gi. Let F be a field of characteristic p. Then f is a nondegenerate skew-symmetric biadditive form defined on each Gi by fi(a,

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil
Deep Underground Science and Engineering, EarlyView.Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

Study on fracture parameter calibration and failure characteristics of rock with hole and crack
Deep Underground Science and Engineering, EarlyView.The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

AIMS MathematicsIn this paper, we consider the symmetry algebra of the geodesic equations of the canonical connection on a Lie group. We mainly consider the solvable indecomposable six-dimensional Lie algebras with co-dimension two abelian nilradical that have an ...

Nonlinear Integrable Couplings of Levi Hierarchy and WKI Hierarchy
Abstract and Applied Analysis, 2014 With the help of the known Lie algebra, a type of new 8-dimensional matrix Lie algebra is constructed in the paper. By using the 8-dimensional matrix Lie algebra, the nonlinear integrable couplings of the Levi hierarchy and the Wadati-Konno-Ichikawa (WKI)

Some properties of Camina and $n$-Baer Lie algebras [PDF]
Journal of Mahani Mathematical ResearchLet $I$ be a non-zero proper ideal of a Lie algebra $L$. Then $(L, I)$ is called a Camina pair if $I \subseteq [x,L]$, for all $x \in L\setminus I$. Also, $L$ is called a Camina Lie algebra if $(L, L^2)$ is a Camina pair. We first give some properties of

Lie algebras and coverings [PDF]
Commentarii Mathematici Helvetici, 1994 Let \(\Lambda\) be an associative unitary finite-dimensional \(\mathbb{C}\)-algebra which is representation finite. This means that the number of isomorphism classes of indecomposable finite-dimensional \(\Lambda\)-left modules is finite. Let us fix a set \(\mathcal F\) of representatives for these isomorphism classes. We showed [\textit{C. Riedtmann},

Differentiated policy implementation in food safety and animal welfare policymaking
European Policy Analysis, EarlyView.Abstract Agri‐food policies are in the midst of far‐reaching transitions, including the transformation towards sustainable production and food consumption. The European Green Deal and Farm to Fork Strategy prioritize food safety and animal welfare issues, aiming to transform food systems towards more sustainability.
