Duality and quasi-normability for complexity spaces

open access: yesApplied General Topology, 2002
The complexity (quasi-metric) space was introduced in [23] to study complexity analysis of programs. Recently, it was introduced in [22] the dual complexity (quasi-metric) space, as a subspace of the function space [0,) ω. Several quasi-metric properties

Non-Abelian Tensor Multiplet Equations from Twistor Space

open access: yes, 2014
We establish a Penrose-Ward transform yielding a bijection between holomorphic principal 2-bundles over a twistor space and non-Abelian self-dual tensor fields on six-dimensional flat space-time.

A note on the minimum‐norm in dual space approach to some classical linear optimal control problems

open access: yesThe Journal of Engineering, 2023
Some classical optimal control problems of linear systems can be characterized as finding minimum‐norm vectors from within linear varieties in appropriate dual spaces.

A Study on Fuzzy Order Bounded Linear Operators in Fuzzy Riesz Spaces

open access: yesMathematics, 2021
This paper aims to study fuzzy order bounded linear operators between two fuzzy Riesz spaces. Two lattice operations are defined to make the set of all bounded linear operators as a fuzzy Riesz space when the codomain is fuzzy Dedekind complete.

New Matrix Domains Arising from the Euler Totient Function and Its Summatory Function

open access: yesDera Natung Government College Research Journal
The matrix formed using the Euler totient function together with its summatory function is employed to generate new sequence spaces. After establishing several features of these spaces, their duals are explicitly identified.

Slant helices, Darboux helices and similar curves in dual space D3 [PDF]

open access: yesMathematica Moravica, 2016
In this paper, we give definitions and characterizations of slant helices, normalized Darboux helices and similar curves in dual space D3. First, we define dual slant helices and dual normalized Darboux helices and show that dual slant helices are also ...

Domain and Function: A Dual-Space Model of Semantic Relations and Compositions [PDF]

open access: yesJournal of Artificial Intelligence Research, 2012
Given appropriate representations of the semantic relations between carpenter and wood and between mason and stone (for example, vectors in a vector space model), a suitable algorithm should be able to recognize that these relations are highly similar ...

Some topological invariants and biorthogonal systems in Banach spaces [PDF]

open access: yes, 2011
We consider topological invariants on compact spaces related to the sizes of discrete subspaces (spread), densities of subspaces, Lindelof degree of subspaces, irredundant families of clopen sets and others and look at the following associations between ...

The celestial chiral algebra of self-dual gravity on Eguchi-Hanson space

open access: yesJournal of High Energy Physics, 2023
We consider the twistor description of classical self-dual Einstein gravity in the presence of a defect operator wrapping a certain ℂℙ1. The backreaction of this defect deforms the flat twistor space to that of Eguchi-Hanson space.

Adiabatic limit and the slow motion of vortices in a Chern-Simons-Schr\"odinger system

open access: yes, 2009
We study a nonlinear system of partial differential equations in which a complex field (the Higgs field) evolves according to a nonlinear Schroedinger equation, coupled to an electromagnetic field whose time evolution is determined by a Chern-Simons term
