The numerical range of positive operators on Hilbert lattices [PDF]

, 2018
We show symmetry properties of the numerical range of positive operators on Hilbert lattices. These results generalise the respective properties for positive matrices shown in Li etal. (Linear Algebra Appl 350:1-23, 2002) and Maroulas etal.

Levy Processes and Quasi-Shuffle Algebras

, 2013
We investigate the algebra of repeated integrals of semimartingales. We prove that a minimal family of semimartingales generates a quasi-shuffle algebra.

Block-pulse functions method for solving three-dimensional fractional Poisson type equations with Neumann boundary conditions

Boundary Value Problems, 2018
In this paper, a numerical scheme based on the three-dimensional block-pulse functions is proposed to solve the three-dimensional fractional Poisson type equations with Neumann boundary conditions.

Memory Hierarchy Behavior Study during the Execution of Recursive Linear Algebra Library

Acta Polytechnica, 2008
For good performance of every computer program, good cache and TLB utilization is crucial. In numerical linear algebra libraries (such as BLAS or LAPACK), good cache utilization is achieved by explicit loop restructuring (mainly loop blocking), but this ...

Image encryption algorithm for crowd data based on a new hyperchaotic system and Bernstein polynomial

IET Image Processing, 2021
A new two‐dimensional chaotic system in the form of a cascade structure is designed, which is derived from the Chebyshev system and the infinite collapse system.

Matrix in Linear Algebra for Modern Computational Solutions

Jurnal Ilmiah Informatika dan Komputer
This study aims to examine the basic concepts of matrix in linear algebra through conceptual and computational approaches. Matrix are understood not only as computational tools, but also as representations of linear transformations and relationships in ...

Unified left eigenvector (ULEV) for blind source separation

Electronics Letters, 2022
A joint analysis method is proposed for source separation from multiple datasets. In this method, sources with the greatest impact on the multiple datasets are identified and then are sequentially separated. The method utilizes the advantage of structure

Strong Tolerance and Strong Universality of Interval Eigenvectors in a Max-Łukasiewicz Algebra

Mathematics, 2020
The Łukasiewicz conjunction (sometimes also considered to be a logic of absolute comparison), which is used in multivalued logic and in fuzzy set theory, is one of the most important t-norms.

Robust static output feedback Nash strategy for uncertain Markov jump linear stochastic systems

IET Control Theory & Applications, 2021
In this article, robust static output feedback (SOF) Nash games for a class of uncertain Markovian jump linear stochastic systems (UMJLSSs) are investigated, in which each player may have access to local/private SOF information.
