Preconditioning complex symmetric linear systems [PDF]

open access: yes, 2014
A new polynomial preconditioner for symmetric complex linear systems based on Hermitian and skew-Hermitian splitting (HSS) for complex symmetric linear systems is herein presented. It applies to Conjugate Orthogonal Conjugate Gradient (COCG) or Conjugate

Linear systems on irregular varieties [PDF]

open access: yes, 2018
Let $X$ be a normal complex projective variety, $T\subseteq X$ a subvariety, $a\colon X\rightarrow A$ a morphism to an abelian variety such that $\rm{Pic}^0(A)$ injects into $\rm{Pic}^0(T)$ and let $L$ be a line bundle on $X$.

Linear Systems over Join-Blank Algebras [PDF]

open access: yes, 2017
A central problem of linear algebra is solving linear systems. Regarding linear systems as equations over general semirings (V,otimes,oplus,0,1) instead of rings or fields makes traditional approaches impossible.

Determination of Romantic Relationship Categories and Investigatıon of Their Dynamical Properties

open access: yesChaos Theory and Applications, 2022
In studies on dynamical modeling of romantic relationships, it is seen that individuals are divided into four different romantic styles. Most of these studies focused on the mathematical analysis of the dynamic expression of individuals' attitudes or ...

Bacterial evolution of antibiotic hypersensitivity

open access: yesMolecular Systems Biology, 2013
The evolution of resistance to a single antibiotic is frequently accompanied by increased resistance to multiple other antimicrobial agents. In sharp contrast, very little is known about the frequency and mechanisms underlying collateral sensitivity.

Stabilisation strategy based on feedback linearisation for DC microgrid with multi-converter

open access: yesThe Journal of Engineering, 2019
Power electronic converters have been widely used in power system and the stability issues of DC microgrid with converters will be discussed in this study. Firstly, an equivalent circuit and the corresponding state space model for DC microgrid with DC–DC
