On a $$\rho $$-Orthogonally Additive Mappings [PDF]
Results in Mathematics, 2020 AbstractWe show that a real normed linear space endowed with the$$\rho $$ρ-orthogonality relation, in general need not be an orthogonality space in the sense of Rätz. However, we prove that$$\rho $$ρ-orthogonally additive mappings defined on some classical Banach spaces have to be additive.

On Symmetric Additive Mappings and Their Applications
Symmetry, 2023 The key motive of this paper is to study symmetric additive mappings and discuss their applications. The study of these symmetric mappings makes it possible to characterize symmetric n-derivations and describe the structure of the quotient ring S/P, where S is any ring and P is a prime ideal of S.

Confins, 2021 Technological advances have turned printed maps into maps that are produced and disseminated in digital environment. Digital maps allow, among other things, changes in symbology, data values and scale of visualization.

Stability of Bi-Additive Mappings and Bi-Jensen Mappings [PDF]
Symmetry, 2021 Symmetry is repetitive self-similarity. We proved the stability problem by replicating the well-known Cauchy equation and the well-known Jensen equation into two variables. In this paper, we proved the Hyers-Ulam stability of the bi-additive functional equation f(x+y,z+w)=f(x,z)+f(y,w) and the bi-Jensen functional equation 4fx+y2,z+w2=f(x,z)+f(x,w)+f(y,

On Identities with Additive Mappings in Rings [PDF]
Iranian Journal of Mathematical Sciences and Informatics, 2020 Summary: If \(F,D:R\rightarrow R\) are additive mappings which satisfy \(F(x^ny^n)=x^ nF(y^n)+y^nD(x^n)\) for all \(x,y\in R\). Then, \(F\) is a generalized left derivation with associated Jordan left derivation \(D\) on \(R\). Similar type of result has been done for the other identity forcing to generalized derivation and at last an example has given

Mapping Spatially Varying Additive Biases in Cosmic Shear Data
The Open Journal of Astrophysics, 2021 In this paper we address the challenge of extracting maps of spatially varying unknown additive biases from cosmic shear data. This is done by exploiting the isotropy of the cosmic shear field, and the anisotropy of a typical additive bias field, using ...

Publications of the Research Institute for Mathematical Sciences, 1988 The set of observables of a Quantum Mechanical System need only be closed under a "quadratic" product. It is shown that an additive structure of this set (whose existence is less natural) is uniquely determined by this multiplicative structure.

Structured additive regression for multicategorical space-time data: A mixed model approach [PDF]
, 2004 In many practical situations, simple regression models suffer from the fact that the dependence of responses on covariates can not be sufficiently described by a purely parametric predictor.

RESULTS ON QUOTIENT NEAR-RINGS INVOLVING ADDITIVE MAPS [PDF]
Journal of Algebraic SystemsWe consider N to be a 3-prime field and P to be a prime ideal of N : In this paper, we studythe commutativity of the quotient ring N =P with left multipliers and derivations satisfying certainidentities on P, generalizing some well-known results in the ...
