Superstability of $m$-additive maps on complete non--Archimedean spaces [PDF]
Sahand Communications in Mathematical Analysis, 2015 The stability problem of the functional equation was conjectured by Ulam and was solved by Hyers in the case of additive mapping. Baker et al. investigated the superstability of the functional equation from a vector space to real numbers.In this paper ...

Additive maps preserving determinant on module of symmetric matrices over Zm [PDF]
Journal of Hebei University of Science and Technology, 2018 In order to characterize the additive maps preserving of modulus of symmetric matrices over residue class rings, these maps are firstly proved to be linear in fact, then they are classified and discussed by means of contract transformation, number theory

Additive Maps on Units of Rings [PDF]
Canadian Mathematical Bulletin, 2018 AbstractLet R be a ring. A map f: R → R is additive if f(a + b) = f(a) + f(b) for all elements a and b of R. Here, a map f: R → R is called unit-additive if f(u + v) = f(u) + f(v) for all units u and v of R. Motivated by a recent result of Xu, Pei and Yi showing that, for any field F, every unit-additive map of (F) is additive for all n ≥ z, this paper

Spreading Process Maps for Powder-Bed Additive Manufacturing Derived from Physics Model-Based Machine Learning [PDF]
Metals, 2019 The powder bed additive manufacturing (AM) process is comprised of two repetitive steps—spreading of powder and selective fusing or binding the spread layer.

Spectrum-preserving additive maps [PDF]
Linear Algebra and its Applications, 1991 Let \(X,Y\) be Banach spaces over the complex field, and \(B(X),B(Y)\) denote the algebra of bounded linear operators on \(X,Y\) respectively. A map \(\Phi: B(X)\to B(Y)\) is said to be spectrum preserving if \(\sigma(\Phi(T))=\sigma(T)\), for every \(T\in B(X)\). The authors prove the following main result.

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.

TRI-ADDITIVE MAPS AND PERMUTING TRI-DERIVATIONS [PDF]
, 2005 In [7] ,Ozturk has proved some results concerning permuting tri-derivations on prime and semi-prime rings.We study permuting tri-additive maps with trace which is skew-commuting or skew-centralizing on s-unital rings and also we obtain a few results on ...
