The Structure of Moduloid on a Nexus
Mathematics, 2019 In this paper, the notion of moduloid on a nexus is introduced. Moreover, the concept of submoduloid is defined and some different submoduloids are introdused. Also, several interesting facts about submoduloids are proved. Finally, a homomorphism between

Locally Split Homomorphisms Relative To A Sub module [PDF]
المجلة العراقية للعلوم الاحصائية, 2013 In this article,for a positive integer n ,the concept of n-locally split homomorphism relative to a sub module has been introduced and studied,which will turn out to be most useful in the studying and providing characterizations of local projectivity ...

The Gelfand map and symmetric products
, 2001 If A is an algebra of functions on X, there are many cases when X can be regarded as included in Hom(A,C) as the set of ring homomorphisms. In this paper the corresponding results for the symmetric products of X are introduced.

Characterization of Pseudo n-Jordan Homomorphisms Between Unital Algebras
پژوهشهای ریاضی, 2020 Let A and B be Banach algebras and B be a right A-module. In this paper, under special hypotheses we prove that every pseudo (n+1)-Jordan homomorphism f:A----> B is a pseudo n-Jordan homomorphism and every pseudo n-Jordan homomorphism is an n-Jordan ...

Failures of weak approximation in families [PDF]
, 2016 Given a family of varieties $X\to \mathbb{P}^n$ over a number field $k$, we determine conditions under which there is a Brauer-Manin obstruction to weak approximation for $100\%$ of the fibres which are everywhere locally soluble.Comment: 44 pages; there

Lefschetz (1,1)-theorem in tropical geometry [PDF]
Épijournal de Géométrie Algébrique, 2018 For a tropical manifold of dimension n we show that the tropical homology classes of degree (n-1, n-1) which arise as fundamental classes of tropical cycles are precisely those in the kernel of the eigenwave map.

On generalized symmetric powers and a generalization of Kolmogorov-Gelfand-Buchstaber-Rees theory
, 2007 The classical Kolmogorov-Gelfand theorem gives an embedding of a (compact Hausdorff) topological space X into the linear space of all linear functionals C(X)^* on the algebra of continuous functions C(X).

Karpatsʹkì Matematičnì Publìkacìï, 2017 It is known that the so-called elementary symmetric polynomials $R_n(x) = \int_{[0,1]}(x(t))^n\,dt$ form an algebraic basis in the algebra of all symmetric continuous polynomials on the complex Banach space $L_\infty,$ which is dense in the Fr\'{e}chet ...

Operators on superspaces and generalizations of the Gelfand-Kolmogorov theorem
, 2007 (Write-up of a talk at the Bialowieza meeting, July 2007.) Gelfand and Kolmogorov in 1939 proved that a compact Hausdorff topological space $X$ can be canonically embedded into the infinite-dimensional vector space $C(X)^* $, the dual space of the ...
