A Theory for Interpolation of Metric Spaces

open access: yesAxioms
In this work, we develop an interpolation theory for metric spaces inspired by the real method of interpolation. These interpolation spaces preserve Lipschitz operators under certain conditions.

Postquantum Br\`{e}gman relative entropies and nonlinear resource theories

open access: yes, 2019
We introduce the family of postquantum Br\`{e}gman relative entropies, based on nonlinear embeddings into reflexive Banach spaces (with examples given by reflexive noncommutative Orlicz spaces over semi-finite W*-algebras, nonassociative L$_p$ spaces ...

Can Computer Algebra be Liberated from its Algebraic Yoke ?

open access: yes, 2005
So far, the scope of computer algebra has been needlessly restricted to exact algebraic methods. Its possible extension to approximate analytical methods is discussed.

Asymptotic Almost Periodic Functions with Range in a Topological Vector Space

open access: yesJournal of Function Spaces and Applications, 2013
The notion of asymptotic almost periodicity was …first introduced by Fréchet in 1941 in the case of …finite dimensional range spaces. Later, its extension to the case of Banach range spaces and locally convex range spaces has been considered by several ...

Differentiability in Fréchet spaces and delay differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
In infinite-dimensional spaces there are non-equivalent notions of continuous differentiability which can be used to derive the familiar results of calculus up to the Implicit Function Theorem and beyond.

On Fuzzy Fréchet Contractions Governed by Rational Expressions and Related Applications

open access: yesJournal of Applied Science and Engineering
. This work explores a specific category of contraction mappings characterized by rational- type within the framework of fuzzy Fréchet spaces(FFS). By utilizing the triangular inequality associated with fuzzy seminorms, we establish fixed point results ...

On I-Fréchet-Urysohn spaces and sequential I-convergence groups [PDF]

open access: yesMathematica Moravica, 2019
In this paper, we introduce the concept of sequential I-convergence spaces and I-Fréchet-Urysohn space and study their properties. We give a sufficient condition for the product of two sequential I-convergence spaces to be a sequential I-convergence ...
