Hahn-Banach Theorem in Vector Spaces
Journal of Mathematical Extension, 2010 . In this paper we introduce a new extension to Hahn-Banach Theorem and consider its relation with the linear operatres.

On the extension of linear operators [PDF]
International Journal of Mathematics and Mathematical Sciences, 2001 It is well known that the Hahn-Banach theorem, that is, the extension theorem for bounded linear functionals, is not true in general for bounded linear operators. A characterization of spaces for which it is true was published by Kakutani in 1940.

A Version of the Hahn-Banach Theorem for R-Vector Spaces [PDF]
Sahand Communications in Mathematical AnalysisRecently, $R$-metric spaces have been introduced to generalized metric spaces. This extension is based on the construction of a new universe with interesting properties.

Hahn-Banach type extension theorems on p-operator spaces [PDF]
Operators and Matrices, 2015 Let $V\subseteq W$ be two operator spaces. Arveson-Wittstock-Hahn-Banach theorem asserts that every completely contractive map $φ:V\to \mathcal{B}(H)$ has a completely contractive extension $\tildeφ:W\to \mathcal{B}(H)$, where $\mathcal{B}(H)$ denotes the space of all bounded operators from a Hilbert space $H$ to itself.

Der Satz von Hahn-Banach per Disjunktionselimination [PDF]
, 2019 The Hahn-Banach extension theorem is at once main pillar of functional analysis and — due to its notorious nature as consequence of the axiom of choice — prime example of a pure existential statement. By way of a general syntactic conservation result for

Dual Spaces and Hahn-Banach Theorem [PDF]
, 2014 In this article, we deal with dual spaces and the Hahn-Banach Theorem. At the first, we defined dual spaces of real linear spaces and proved related basic properties. Next, we defined dual spaces of real normed spaces.

An extension of Helson-Edwards theorem to Banach Modules [PDF]
, 1991 An extension of the Helson-Edwards theorem for the group algebras to Banach modules over commutative Banach algebras is given. This extension can be viewed as a generalization of Liu-Rooij-Wang's result for Banach modules over the group ...

Identification and Estimation of Large Network Games with Private Link Information
International Economic Review, Volume 67, Issue 2, Page 411-432, May 2026.ABSTRACT We study the identification and estimation of large network games in which individuals choose continuous actions while holding private information about their links and payoffs. Extending the framework of Galeotti et al., we build a tractable empirical model of such network games and show that the parameters in individual payoffs are ...

Potential trace inequalities via a Calderón‐type theorem
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract In this paper, we develop a general theoretical tool for the establishment of the boundedness of notoriously difficult operators (such as potentials) on certain specific types of rearrangement‐invariant function spaces from analogous properties of operators that are easier to handle (such as fractional maximal operators).
