On Supra-Additive and Supra-Multiplicative Maps [PDF]

open access: yesJournal of Function Spaces and Applications, 2013
Let A and B be ordered algebras over ℝ, where A has a generating positive cone and B satisfies the property that b2>0 if 0≠b∈B. We give some conditions for a map T:A→B which is supra-additive and supra-multiplicative for all positive and negative ...

THE NEARLY ADDITIVE MAPS [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2009
This note is a verification on the relations between almost lin- ear and nearly additive maps; and the continuity of almost multiplicative nearly additive maps. Also we consider the stability of nearly additive and almost linear maps.

A simple model captures key characteristics of biological non-deterministic genotype-phenotype maps. [PDF]

open access: yesPLoS Computational Biology
By connecting genotypic mutations to the higher-level phenotypes relevant for selection, genotype-phenotype (GP) maps play a key role in evolution. GP maps are typically investigated using computational models of biophysical phenotypes (for example, RNA ...

On a $$\rho $$-Orthogonally Additive Mappings [PDF]

open access: yesResults 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

open access: yesSymmetry, 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.

Stability of Bi-Additive Mappings and Bi-Jensen Mappings [PDF]

open access: yesSymmetry, 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,

Influência do uso do intervalo HSV na capacidade de diferenciação da variável visual cor em mapas corocromáticos visualizados em meio digital

open access: yesConfins, 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.

On Identities with Additive Mappings in Rings [PDF]

open access: yesIranian 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

open access: yesThe 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 ...

Additivity of Quadratic Maps

open access: yesPublications 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.
