Automorphic Lie algebras with dihedral symmetry [PDF]
, 2014 The concept of automorphic Lie algebras arises in the context of reduction groups introduced in the early 1980s in the field of integrable systems.

The role of identification in data‐driven policy iteration: A system theoretic study
International Journal of Robust and Nonlinear Control, EarlyView.Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

In this paper, we introduce the notion of $q$-pre-Lie algebras from the perspective of representations of Lie algebras, providing a parametrized generalization that unifies pre-Lie algebras and anti-pre-Lie algebras. For a $q$-pre-Lie algebra $(A,\circ)$, the commutator of $\circ$ is a Lie bracket and the left multiplication operator scaled by $q ...

A rigidity theorem for pre-Lie algebras
Journal of Pure and Applied Algebra, 2006 The starting point of the paper under review is the classical Leray theorem that any graded connected commutative and cocommutative Hopf algebra is a free commutative algebra and a free cocommutative coalgebra and its analogues for unital infinitesimal bialgebras [\textit{J.-L. Loday} and \textit{M. Ronco}, J. Reine Angew. Math.

Responsive Materials, EarlyView.Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Spaceborne Distributed Array Processing for Precision Source Localization
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Satellite‐based signals intelligence and spectrum sensing increasingly rely on low‐latency signal localization. However, operational processing chains often remain ground‐based, stressing feeder links and limiting scalability as constellations grow.

On nilpotency in pre - Lie algebras
The authors consider several variants of the notion of nilpotency in pre-Lie algebras and investigate the properties of nilpotent ideals.

Sustainable Development, EarlyView.ABSTRACT Infrastructure‐led development in rapidly urbanizing economies often generates accessibility gains that fail to translate into balanced urban outcomes, particularly when local fiscal institutions redirect those gains toward revenue‐generating land uses. Filling this gap, especially in fiscally constrained county‐level cities where land finance

Sustainable Development, EarlyView.ABSTRACT Declining natural resources, rising production costs, and diminishing returns from input‐intensive practices threaten the sustainability of smallholder rice systems in Bangladesh. Using a primal system approach and survey data from 1869 rice‐producing households, this study evaluates technical and allocative inefficiency across major agro ...

The Mitigating Role of Managerial Ability in ESG Decoupling
Sustainable Development, EarlyView.ABSTRACT Does managerial competence widen or bridge the gap between environmental, social, and governance (ESG) disclosures and actual performance? This paper explores the relationship between CEO ability and corporate decoupling regarding sustainability issues.
