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

The Archimedean order unitization of seminormed ordered vector spaces [PDF]
Positivity (Dordrecht), 2022 In this paper, we describe a way of turning a seminormed preordered vector space into an Archimedean order unit space. We show that this construction satisfies a universal property similar to that of the Archimedeanization of Paulsen and Tomforde, and we

CHARACTERISATION OF EQUIVALENT NORMS ON A LINEAR SPACE USING EXPONENTIAL VECTOR SPACE [PDF]
South East Asian J. of Mathematics and Mathematical Sciences, 2023 In this paper we have found a necessary and sufficient condition for equivalence of two norms on a linear space using the theory of exponential vector space.

Component graphs of vector spaces and zero-divisor graphs of ordered sets [PDF]
AKCE Int. J. Graphs Comb., 2022 In this paper, nonzero component graphs and nonzero component union graphs of finite dimensional vector space are studied using the zero-divisor graph of specially constructed 0-1-distributive lattice and the zero-divisor graph of rings.

A Partial Order OWA Operator for Solving the OWA Weighing Dilemma
IEEE 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.

Semi-order Continuous Operators on Vector Spaces [PDF]
Bulletin 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 $W$.

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