Semipositivity with respect to the Lorentz cone

The Electronic Journal of Linear Algebra, 2023
Lorentz cone in the Euclidean space $\mathbb{R}^{n}$ is defined as $\mathcal{L}^n_+:=\{x\in \mathbb{R}^n:x_n\geq 0,\sum\limits_{i=1}^{n-1}x_{i}^2\leq x_n^2\}$. The paper aims to study semipositivity of matrices with respect to $\mathcal{L}^n_+$.

Vector-Valued Spaces of Multiplier Statistically Convergent Series and Uniform Convergence [PDF]

, 2022
[EN] In this paper, we introduce the spaces of vector-valued sequences containing multiplier (weakly) statistically convergent series. The completeness of such spaces is studied as well as some relations between unconditionally convergent and weakly ...

Some isomorphic properties in projective tensor products [PDF]

, 2022
summary:We give sufficient conditions implying that the projective tensor product of two Banach spaces $X$ and $Y$ has the $p$-sequentially Right and the $p$-$L$-limited properties, $1\le ...

The isothermal evolution of nanoporous gold from the ring perspective - an application of graph theory

, 2020
The ring structures of five isothermally annealed nanoporous gold (npg) samples were analyzed explicitly by applying results and algorithms from graph theory to skeletonized 3D reconstructions from focused ion beam (FIB) tomography data.

Total and Local Quadratic Indices of the Molecular Pseudograph’s Atom Adjacency Matrix: Applications to the Prediction of Physical Properties of Organic Compounds

Molecules, 2003
A novel topological approach for obtaining a family of new molecular descriptors is proposed. In this connection, a vector space E (molecular vector space), whose elements are organic molecules, is defined as a “direct sum” of different ℜi spaces.
