On orthogonally additive mappings, IV

open access: yesAequationes Mathematicae, 1989
[For part II see the first author, Publ. Math. 35, No.3/4, 241-249 (1988; reviewed above).] Let \(\Phi\) denote a field of characteristic \(\neq 2\), X a \(\Phi\)-vector space of dimension \(\geq 2\) and \((Y,+)\) an abelian group. Furthermore let \(\perp\), which is called orthogonality on X, be a binary relation satisfying certain appropriate ...

Genetic dissection of husk number and length across multiple environments and fine-mapping of a major-effect QTL for husk number in maize (Zea mays L.)

open access: yesCrop Journal, 2020
Husk number (HN) and husk length (HL) influence the mechanical harvesting of maize grain. We investigated the genetic basis of HN and HL using a population of 204 recombinant inbred lines phenotypically evaluated in five environments. The two husk traits

A new mapping method for quantitative trait loci of silkworm

open access: yesBMC Genetics, 2011
Background Silkworm is the basis of sericultural industry and the model organism in insect genetics study. Mapping quantitative trait loci (QTLs) underlying economically important traits of silkworm is of high significance for promoting the silkworm ...

Quasi-additive mappings

open access: yesJournal of Mathematical Analysis and Applications, 2004
A map \(f\) between Abelian topological groups is called quasi-additive if the function of two variables \(f(x+y)-f(x)-f(y)\) is continuous at the origin. Obvious examples are additive maps, maps which are continuous at the origin, and sums of such maps.

Bayesian Geoadditive Seemingly Unrelated Regression [PDF]

open access: yes, 2002
Parametric seemingly unrelated regression (SUR) models are a common tool for multivariate regression analysis when error variables are reasonably correlated, so that separate univariate analysis may result in inefficient estimates of covariate effects. A

On a Functional Equation Related to Information Theory

open access: yesRatio Mathematica, 2017
The general solutions of a functional equation, without imposing any regularity condition on the mappings appearing in it, have been obtained. One solution of this functional equation is useful from information-theoretic point of view.

Generalized Hyers-Ulam-Rassias Theorem in Menger Probabilistic Normed Spaces

open access: yesDiscrete Dynamics in Nature and Society, 2010
We introduce two reasonable versions of approximately additive functions in a Šerstnev probabilistic normed space endowed with Π𝑀 triangle function. More precisely, we show under some suitable conditions that an approximately additive function can be ...

Additive Realizations of Asymptotically Additive Set Maps

open access: yesCommunications in Mathematical Physics
Given a countable discrete amenable group, we study conditions under which a set map into a Banach space (or more generally, a complete semi-normed space) can be realized as the ergodic sum of a vector under a group representation, such that the realization is asymptotically indistinguishable from the original map.

On stability of additive mappings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
In this paper we answer a question of Th. M. Rassias concerning an extension of validity of his result proved in [3].
