The Parallel Tiled WZ Factorization Algorithm for Multicore Architectures
International Journal of Applied Mathematics and Computer Science, 2019 The aim of this paper is to investigate dense linear algebra algorithms on shared memory multicore architectures. The design and implementation of a parallel tiled WZ factorization algorithm which can fully exploit such architectures are presented. Three

Numerical linear algebra in data assimilation
GAMM-Mitteilungen, 2020 AbstractData assimilation is a method that combines observations (ie, real world data) of a state of a system with model output for that system in order to improve the estimate of the state of the system and thereby the model output. The model is usually represented by a discretized partial differential equation.

New error bounds for linear complementarity problems of Σ-SDD matrices and SB-matrices
Open Mathematics, 2019 A new error bound for the linear complementarity problem (LCP) of Σ-SDD matrices is given, which depends only on the entries of the involved matrices. Numerical examples are given to show that the new bound is better than that provided by García-Esnaola ...

Geometric Characterization of the Numerical Range of Parallel Sum of Two Orthogonal Projections
Journal of MathematicsLet H be a complex separable Hilbert space and BH be the algebra of all bounded linear operators from H to H. Our goal in this article is to describe the closure of numerical range of parallel sum operator P:PQ for two orthogonal projections P and Q in ...

Correlated dynamics of immune network and sl(3, R) symmetry algebra
Computational and Mathematical BiophysicsWe observed the existence of periodic orbits in immune network under transitive solvable Lie algebra. In this article, we focus to develop condition of maximal Lie algebra for immune network model and use that condition to construct a vector field of ...
