3-Leibniz bialgebras (3-Lie bialgebras)

open access: yes, 2017
The aim of this paper is to extend the notion of bialgebra for Leibniz algebras (and Lie algebras) to $3$-Leibniz algebras (and $3$-Lie algebras) by use of the cohomology complex of $3$-Leibniz algebras.

Leibniz

open access: yesIntuitio, 2022
De acordo com Gottfried Wilhelm Leibniz para compreender as substâncias individuais devemos distanciar-nos e ver a totalidade. De facto, é preciso ver o quadro à distância conveniente para compreender a perfeição da totalidade e da singularidade. A possível saída do labirinto no qual a metafísica nos enredou, estimula o desejo de conhecer tudo e a ...

“Plus simple et plus facile que quelque chose” . Le rien et la raison suffisante De Leibniz à Kant

open access: yesLexicon Philosophicum, 2021
From Leibniz’ point of view, the distinction between nature and grace is stripped of all theological reference: the key to reading the Principles of Nature and Grace (PNG) seems to be found, at the beginning of §7, in the distinction between the physical

On the Leibniz bracket, the Schouten bracket and the Laplacian

open access: yes, 2003
The Leibniz bracket of an operator on a (graded) algebra is defined and some of its properties are studied. A basic theorem relating the Leibniz bracket of the commutator of two operators to the Leibniz bracket of them, is obtained.

On the structure of Leibniz algebras, whose subalgebras are ideals or core-free

open access: yesДоповiдi Нацiональної академiї наук України
An algebra L over a field F is said to be a Leibniz algebra (more precisely, a left Leibniz algebra), if it satisfies the Leibniz identity: [[a, b], c] = [a, [b, c]] — [b, [a, c]] for all a, b, c ∈ L. Leibniz algebras are generalizations of Lie algebras.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Toland and Locke in the Leibniz-Burnett Correspondence

open access: yesLocke Studies, 2018
Thomas Burnett of Kemnay (1656-1729), who corresponded with Leibniz for several years, is perhaps best known to historians of philosophy as one of those via whom Leibniz tried to communicate with Locke.

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Leibniz Algebras and Lie Algebras

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
This paper concerns the algebraic structure of finite-dimensional complex Leibniz algebras. In particular, we introduce left central and symmetric Leibniz algebras, and study the poset of Lie subalgebras using an associative bilinear pairing taking ...

On the homological properties of the universal enveloping Leibniz algebra [PDF]

open access: yes, 2018
We presente a study of graded Leibniz algebras and its universal enveloping Leibniz algebra. We prove that the universal enveloping Leibniz algebra of a finite dimensional graded Leibniz algebra is a quasi-Koszul algebra or an inhomogeneous Koszul ...
