Unbounded Order Convergence in Ordered Vector Spaces

open access: yesJournal of Mathematics
We consider an ordered vector space X. We define the net xα⊆X to be unbounded order convergent to x (denoted as xα⟶uox). This means that for every 0≤y∈X, there exists a net yβ (potentially over a different index set) such that yβ↓0, and for every β ...

Algebraic characterisation of hyperspace corresponding to topological vector space [PDF]

open access: yesJournal of Hyperstructures, 2023
Let X be a Hausdor  topological vector space over the field of real or complex numbers. When Vietoris topology is given,the hyperspace ℘(X) of all nonempty compact subsets of X forms a topological exponential vector space over the same field. Exponential

Ordered Vectorial Quasi and Almost Contractions on Ordered Vector Metric Spaces

open access: yesMathematics, 2021
In this paper, we define ordered vectorial quasi contractions. We show that ordered quasi contractions are ordered vectorial quasi contractions, but the reverse is not true.

Ordered vector spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1952
Simple consequences of these assumptions are: x>y implies x+z >y+z;x>y implies Xx>Xy for real positive scalarsX; x > 0 if and only if 0>-x. An important class of examples of such V's is due to R. Thrall ; we shall call these spaces lexicographic function spaces (LFS), defining them as follows: Let T be any simply ordered set ; let / be any real-valued ...

Semi-order Continuous Operators on Vector Spaces [PDF]

open access: yesBulletin of the Iranian Mathematical Society, 2021
In this manuscript, we will study both $\tilde{o}$-convergence in (partially) ordered vector spaces and a kind of convergence in a vector space $V$. A vector space $V$ is called semi-order vector space (in short semi-order space), if there exist an ordered vector space $W$ and an operator $T$ from $V$ into $W$.

A Partial Order OWA Operator for Solving the OWA Weighing Dilemma

open access: yesIEEE Access, 2023
Prior weights are necessary for the application of ordered weighted averaging (OWA) operators, but obtaining them is expensive and contentious, which restricts the application of operators.

Bochner integrals in ordered vector spaces [PDF]

open access: yesPositivity, 2016
We present a natural way to cover an Archimedean directed ordered vector space E by Banach spaces and extend the notion of Bochner integrability to functions with values in E. The resulting set of integrable functions is an Archimedean directed ordered vector space and the integral is an order preserving map.

Improving Ship Detection Based on Decision Tree Classification for High Frequency Surface Wave Radar

open access: yesJournal of Marine Science and Engineering, 2023
The traditional constant false alarm rate (CFAR) method, with fixed parameter settings and single noise background calculation, is unable to intelligently catch the current detection background.

Independence, infinite dimension, and operators

open access: yesMoroccan Journal of Pure and Applied Analysis, 2023
In [Appl. Comput. Harmon. Anal., 46 (2019), 664673] O. Christensen and M. Hasannasab observed that assuming the existence of an operator T sending en to en+1 for all n ∈ ℕ (where (en)n∈ℕ is a sequence of vectors) guarantees that (en)n∈ℕ is linearly ...
