On Additive Maps and Commutativity in Rings

Results in Mathematics, 1999
Various results concerning (skew-)commuting and skew-centralizing maps on (semi)prime rings are obtained. A sample result: Let \(R\) be a 2-torsionfree semiprime ring, \(U\) be a nonzero left ideal of \(R\) and \(d\) be a derivation of \(R\). If \(d\) is skew-commuting on \(U\) (that is, \(ud(u)+d(u)u=0\) for all \(u\in U\)), then \(d(U)=0\).

Additions to the exclusion map of man

Pathology, 1981
Exclusion mapping was applied to individuals with monosomic segments defined by chromosomal banding. A range of genetic markers and blood groups was determined resulting in new exclusions for unassigned markers at the following segments : (3)(p25 leads to pter) - JK, GPT, PI ; (4)(127 leads to 31) - MNS, JK, PI, C3, F13A, F13B ; (7))q22) - LU, F13A ...

The adjoint of an additive map

Il Nuovo Cimento B, 1986
It is proved that the mapping which assigns to a bounded additive map from one complex Banach space to another its adjoint is an additive monomorphism. It is shown that differences in the structures of continuous additive maps on a complex Banach space and of linear maps on a real Banach space are not trivial.

On orthogonally additive mappings. II

Publicationes Mathematicae Debrecen, 1989
[For part I see Aequationes Math. 28, 35-49 (1985; Zbl 0569.39006).] Let \({\mathfrak K}\) be an ordered field, \({\mathfrak X}\) a \({\mathfrak K}\)-vector space with \(\dim_{{\mathfrak K}}{\mathfrak X}\geq 2\), and \(\perp\) a binary relation on \({\mathfrak X}\) with four appropriate properties.

φ-Orthogonally additive mappings. I

Acta Mathematica Hungarica, 1991
From author's introduction: This is the second part of a series of papers describing the properties of \(\phi\)-orthogonally additive mappings for a sesquilinear form \(\phi\). While in the first part the symmetric orthogonality has been studied, here we examine the cases of non- symmetric and totally isotropic orthogonalities, showing essentially the ...

Additive Nearest Neighbor Feature Maps

2015 IEEE International Conference on Computer Vision (ICCV), 2015
In this paper, we present a concise framework to approximately construct feature maps for nonlinear additive kernels such as the Intersection, Hellinger's, and χ2 kernels. The core idea is to construct for each individual feature a set of anchor points and assign to every query the feature map of its nearest neighbor or the weighted combination ...

When are ∨-additive mappings multiplicative?

Journal of Algebra and Its Applications
In the spirit of some earlier studies of the authors, we discuss the alienation problem for ∨-additive and multiplicative mappings. This study enables us to answer two questions that were left open in [B. Al Subaiei and N. Jarboui, On the monoid of unital endomorphisms of a Boolean ring, Axioms 10(4) (2021) 305].

Additivity of Quadratic Maps on JB Algebras

Lobachevskii Journal of Mathematics, 2019
In line with several results ranging from operator algebras to ring theory, this paper discusses automatic additivity of maps satisfying particular multiplicative properties, thereby outlining an entangling between the multiplicative and additive structures. The structures under scrutiny are JB-algebras and quadratic maps between them: for JB-algebras \

SiZer Map for inference with additive models

Statistics and Computing, 2008
Sizer Map is proposed as a graphical tool for assistance in nonparametric additive regression testing problems. Four problems have been analyzed by using SiZer Map: testing for additivity, testing the components significance, testing parametric models for the components and testing for interactions.

On additive maps of prime rings. II.

Publicationes Mathematicae Debrecen, 1999
[For part I see the authors, Bull. Aust. Math. Soc. 51, No. 3, 377-381 (1995; Zbl 0833.16016).] The authors determine the form of maps \(f_1,\dots,f_n\) of \(R\) (a prime ring) satisfying \[ f_1(x)x^{n-1}+xf_2(x)x^{n-2}+\cdots+x^{n-1}f_n(x)=0.\tag{1} \] If \(R\) is a prime ring then \(Z\), \(C\), \(RC\) are the center, the extended centroid and the ...
