Nonlinear Jordan Derivable Mappings of Generalized Matrix Algebras by Lie Product Square-Zero Elements

open access: yesJournal of Mathematics, 2021
The aim of the paper is to give a description of nonlinear Jordan derivable mappings of a certain class of generalized matrix algebras by Lie product square-zero elements.

Jordan Algebras Over Algebraic Varieties [PDF]

open access: yesCommunications in Algebra, 2010
We construct Jordan algebras over a locally ringed space using generalizations of the Tits process and the first Tits construction by Achhammer. Some general results on the structure of these algebras are obtained. Examples of Albert algebras over a Brauer-Severi variety with associated central simple algebra of degree 3 are given.

Masking Ability of CAD‐CAM Materials at Different Thicknesses: A Study on Color, Translucency, and Infinite Optical Thickness

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the masking ability of different thicknesses of CAD‐CAM resin‐matrix and feldspar porcelain materials. Materials and Methods Specimens (Ø7.5 mm, thickness 0.5, 1.0, and 1.5 mm, n = 3/material) were fabricated from Lava Ultimate‐LU, Grandio Blocs‐GB, VITA Enamic‐VE, and VITA Mark II‐VM.

Maximum Entropy and Sufficiency

open access: yes, 2016
The notion of Bregman divergence and sufficiency will be defined on general convex state spaces. It is demonstrated that only spectral sets can have a Bregman divergence that satisfies a sufficiency condition.

The fundamental theorem of asset pricing with and without transaction costs

open access: yesMathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.
Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...

Does policy design matter for the effectiveness of local content requirements? A qualitative comparative analysis of renewable energy value chains

open access: yesPolicy Studies Journal, EarlyView.
Abstract Green industrial policies aim to create local value from renewable energy (RE) technologies. One policy instrument includes local content requirements (LCR), which prescribe a minimum share of locally manufactured inputs for investments in RE. However, the policy effectiveness of LCR differs.

On the structure of split regular -Hom-Jordan-Lie superalgebras

open access: yesBoletim da Sociedade Paranaense de Matemática, 2022
In this paper we study the structure of arbitrary split regular -Hom-Jordan-Lie super algebras. By developing techniques of connections of roots for this kind of algebras, we show that such a split regular -Hom-Jordan-Lie superalgebra L is of the form

When Do Authoritarian Regimes Use Digital Technologies for Covert Repression? A Qualitative Comparative Analysis of Politico‐Economic Conditions

open access: yesSwiss Political Science Review, EarlyView.
Abstract Although autocracies increasingly learn how to integrate digital technologies into their covert repression toolbox, it remains unclear under which conditions they succeed in doing so. While some technologically developed autocracies seldom use covert repression, other technologically underdeveloped autocracies apply significantly more covert ...

On the constructions of Tits and Faulkner: an isomorphism theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
Classification theory guarantees the existence of an isomorphism between any two E8's, at least over an algebraically closed field of characteristic 0.
