A Lie Bracket for the Momentum Kernel [PDF]

open access: yesCommunications in Mathematical Physics, 2020
We prove results for the study of the double copy and tree-level colour/kinematics duality for tree-level scattering amplitudes using the properties of Lie polynomials.

LaraDB: A Minimalist Kernel for Linear and Relational Algebra Computation [PDF]

open access: yesBeyondMR@SIGMOD, 2017
Analytics tasks manipulate structured data with variants of relational algebra (RA) and quantitative data with variants of linear algebra (LA). The two computational models have overlapping expressiveness, motivating a common programming model that ...

Kernel charge equilibration: efficient and accurate prediction of molecular dipole moments with a machine-learning enhanced electron density model

open access: yesMachine Learning: Science and Technology, 2021
State-of-the-art machine learning (ML) interatomic potentials use local representations of atomic environments to ensure linear scaling and size-extensivity.

L-Fuzzy Congruences and L-Fuzzy Kernel Ideals in Ockham Algebras

open access: yesJournal of Mathematics, 2021
In this paper, we study fuzzy congruence relations and kernel fuzzy ideals of an Ockham algebra A,f, whose truth values are in a complete lattice satisfying the infinite meet distributive law.

On the Torelli Lie algebra

open access: yesForum of Mathematics, Pi, 2023
We prove two theorems about the Malcev Lie algebra associated to the Torelli group of a surface of genus g: Stably, it is Koszul and the kernel of the Johnson homomorphism consists only of trivial $\mathrm {Sp}_{2g}(\mathbb {Z})$ -representations ...

Neutrosophic Vague Binary G-subalgebra of G-algebra [PDF]

open access: yesNeutrosophic Sets and Systems, 2020
Nowadays, human society is using artificial intelligence in a large manner so as to upgrade the present existing applicational criteria’s and tools. Logic is the underlying principle to these works. Algebra is inevitably inter-connected with logic. Hence

On the congruence kernel for simple algebraic groups [PDF]

open access: yesProceedings of the Steklov Institute of Mathematics, 2016
This paper contains several results about the structure of the congruence kernel C^(S)(G) of an absolutely almost simple simply connected algebraic group G over a global field K with respect to a set of places S of K. In particular, we show that C^(S)(G) is always trivial if S contains a generalized arithmetic progression.

Alpha Ideals and the Space of Prime Alpha Ideals in Universal Algebras

open access: yesJournal of Mathematics, 2021
The purpose of this paper is to study α-ideals in a more general context, in universal algebras having a constant 0. Several characterizations are obtained for an ideal I of an algebra A to be an α-ideal.

Decomposition of Finitely Additive Markov Chains in Discrete Space

open access: yesMathematics, 2022
In this study, we consider general Markov chains (MC) defined by a transition probability (kernel) that is finitely additive. These Markov chains were constructed by S. Ramakrishnan within the concepts and symbolism of game theory.
