On multiplicative (strong) linear preservers of majorizations [PDF]
Sahand Communications in Mathematical Analysis, 2016 In this paper, we study some kinds of majorizations on $textbf{M}_{n}$ and their linear or strong linear preservers. Also, we find the structure of linear or strong linear preservers which are multiplicative, i.e.

Linear preservers of acu-majorization on $\mathbb{R}^3$ and $M_{3,m}$ [PDF]
Journal of Mahani Mathematical ResearchIn this note, we present an equivalent condition for linear preservers of group majorization induced by closed subgroup $G$ of $O(\mathbb{R}^n)$. Moreover, a new concept of majorization is defined on $\mathbb{R}^3$ as acu-majorization and this is ...

Latin-majorization and its linear preservers [PDF]
Sahand Communications in Mathematical Analysis, 2017 In this paper we study the concept of Latin-majorizati-\on. Geometrically this concept is different from other kinds of majorization in some aspects.

Linear Preservers of Chain Majorization
Journal of Mathematical Extension, 2008 For (n×m matrices) X, Y ∈ Mnm(R)(= Mnm), we say X is chain majorized by Y and write X ≺≺ Y if X = RY where R is a product of finitely many T-transforms. A linear operator T : Mnm → Mnm is said to be a linear preserver of the relation ≺≺ on Mnm if X ≺≺

To preserve or not to preserve [PDF]
Cancer, 2013 BACKGROUNDThe decision to pursue fertility preservation (FP) after a cancer diagnosis is complex. We examined the prevalence of high decisional conflict and specific factors that influence this decision using the Decisional Conflict Scale (DCS).METHODSThe FIRST project is a web‐based survey of female cancer survivors (ages 18‐44 years) who have ...

Comparison of natural durability of wood by stake tests followed by survival analysis
Journal of Wood Science, 2021 The conventional stake test is widely used to evaluate wood durability. The test monitors the deterioration level observed on stakes partially inserted into the ground.

Religion and settlement as preservers of ethnicity [PDF]
Glasnik Etnografskog Instituta SANU, 2004 A separate ethnic group living in an isolated settlement could preserve ethnic identity even when surrounded by an alien ethnic environment. This is even more likely to happen if the ethnic group in question has a different religious affiliation than the

Journal of Symbolic Logic, 2005 AbstractWe prove that the property “P doesn't make the old reals Lebesgue null” is preserved under countable support iterations of proper forcings, under the additional assumption that the forcings are nep (a generalization of Suslin proper) in an absolute way. We also give some results for general Suslin ccc ideals.

Quantum, 2020 Resource theory is a general, model-independent approach aiming to understand the qualitative notion of resource quantitatively. In a given resource theory, free operations are physical processes that do not create the resource and are considered zero-cost.

A note on $2$-plectic vector spaces [PDF]
Journal of Mahani Mathematical Research, 2023 Among the $2$-plectic structures on vector spaces, the canonical ones and the $2$-plectic structures induced by the Killing form on semisimple Lie algebras are more interesting.
