Open partial isometries and positivity in operator spaces [PDF]

open access: yes, 2007
We study positivity in C*-modules and operator spaces using open tripotents, and an ordered version of the `noncommutative Shilov boundary'. Because of their independent interest, we also systematically study open tripotents and their properties.Comment:

Linear Transformations between Multipartite Quantum Systems That Map the Set of Tensor Product of Idempotent Matrices into Idempotent Matrix Set

open access: yesJournal of Function Spaces and Applications, 2013
Let Hn be the set of n×n complex Hermitian matrices and 𝒫n (resp., 𝒯n) be the set of all idempotent (resp., tripotent) matrices in Hn. In l-partite quantum system Hm1Tml=⊗1lHmi, ⊗1l𝒫mi (resp., ⊗1l𝒯mi) denotes the set of all decomposable elements ⊗1lAi ...

Proper holomorphic maps between bounded symmetric domains revisited

open access: yes, 2014
We prove that a proper holomorphic map between two bounded symmetric domains of the same dimension, one of them being irreducible, is a biholomorphism.

Weakly quadratent rings

open access: yesJournal of Taibah University for Science, 2019
We completely characterize up to an isomorphism those rings whose elements satisfy the equations $ x^4=x $ or $ x^4=-x $ . Specifically, it is proved that a ring is weakly quadratent if, and only if, it is isomorphic to either K, $ \mathbb {Z}_3 ...

Tripotential differentiation of adherently expandable neural stem (NS) cells.

open access: yesPLoS ONE, 2007
BackgroundA recent study has shown that pure neural stem cells can be derived from embryonic stem (ES) cells and primary brain tissue. In the presence of fibroblast growth factor 2 (FGF2) and epidermal growth factor (EGF), this population can be ...

Holomorphic isometries from the unit ball into symmetric domains

open access: yes, 2017
We construct isometric holomorphic embeddings of the unit ball into higher rank symmetric domains, first discovered by Mok, in an explicit way using Jordan triple systems, and prove uniqueness results for all domains, including the exceptional domains of

Generalizing Semi-n-Potent Rings

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
The present article deals with the problem of characterizing a widely large class of associative and possibly non-commutative rings. So, we define and explore the class of rings R for which each element in R is a sum of a tripotent element from R and an

Dye’s theorem for tripotents in von Neumann algebras and JBW$$^*$$-triples [PDF]

open access: yesBanach Journal of Mathematical Analysis, 2021
We study morphisms of the generalized quantum logic of tripotents in JBW*-triples and von Neumann algebras. Especially, we establish generalization of celebrated Dye's theorem on orthoisomorphisms between von Neumann lattices to this new context. We show one-to-one correspondence between maps on tripotents preserving orthogonality, orthogonal suprema ...
