Characterization of the order relation on the set of completely n-positive linear maps between C^*-algebras [PDF]

Surveys in Mathematics and its Applications, 2007
In this paper we characterize the order relation on the set of all nondegenerate completely n-positive linear maps between C*-algebras in terms of a self-dual Hilbert module induced by each completely n-positive linear map.

Positive linear maps and perturbation bounds of matrices

Linear Algebra and its Applications, 2017
We show how positive unital linear maps can be used to obtain lower bounds for the maximum distance between the eigenvalues of two normal matrices. Some related bounds for the spread and condition number of Hermitian matrices are also discussed here.

Ewing Sarcoma in Infants and Children Under 2 Years of Age: A French Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ewing sarcoma, the second most common primary bone cancer in children, requires intensive treatment that may lead to significant long‐term sequelae, particularly in infants. We retrospectively analyzed data from 1621 French patients treated between 1988 and 2015 within the EW88/93/97 or EE99 trials, focusing on 17 infants diagnosed before 24 ...

Design of PDC Controllers by Matrix Reversibility for Synchronization of Yin and Yang Chaotic Takagi-Sugeno Fuzzy Henon Maps

Abstract and Applied Analysis, 2012
This paper investigates the synchronization of Yin and Yang chaotic T-S fuzzy Henon maps via PDC controllers. Based on the Chinese philosophy, Yin is the decreasing, negative, historical, or feminine principle in nature, while Yang is the increasing ...

Topological methods on solvability, multiplicity and bifurcation of a nonlinear fractional boundary value problem

Electronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, we first prove new properties of the $(a, q)$-stably solvable maps for a class of decomposable operators in the form of $LF$, where $L$ is a bounded linear operator and $F$ is nonlinear.
