Some inequalities for positive linear maps
Linear Algebra and its Applications, 2012 Let \(M_{n}( \mathbb{C} )\) be the algebra of all \(n\times n\) complex matrices and let \(\phi :M_{n}( \mathbb{C} )\rightarrow M_{n}( \mathbb{C} )\) be a positive unital map. The authors prove that if \(A\in M_{n}( \mathbb{C} )\), then \[ \phi (A^{\ast }A)-\phi (A)^{\ast }\phi (A)\leq \inf_{z\in \mathbb{C} }\left\| A-z\right\|.

Reducing the Dimensionality of SPD Matrices with Neural Networks in BCI
Mathematics, 2023 In brain–computer interface (BCI)-based motor imagery, the symmetric positive definite (SPD) covariance matrices of electroencephalogram (EEG) signals with discriminative information features lie on a Riemannian manifold, which is currently attracting ...

Extreme positive linear maps onC *-algebras
Mathematische Zeitschrift, 1988 Let A be a unital \(C^ *\)-algebra and let B be a von Neumann algebra. Let S(A,B) be the convex set of unital positive linear maps between A and B. We prove that the extreme points of S(A,B) are exactly the unital algebra homomorphisms if and only if A is abelian and, either B is abelian or dim A\(

On positive linear maps preserving invertibility
Journal of Functional Analysis, 1984 A positive linear map \(\Phi\) between two \(C^*\)-algebras is a Jordan homomorphism if \(\Phi\) preserves invertibility and the range of \(\Phi\) is a \(C^*\)-algebra. A counterexample is given for the case that the range of \(\Phi\) is not assumed to be a \(C^*\)-algebra; this answers a question raised by \textit{B. Russo} [Proc. Am. Math. Soc.

Positive linear maps on operator algebras [PDF]
Communications in Mathematical Physics, 1976 Given a family of completely positive maps, indexed by a group, from aC*-algebra into itself, we are concerned with its dilation to a group of *-automorphisms on a larger algebra. A Schwarz-type inequality forn-positive *-linear mappings from an involutive algebra into the bounded linear operators on a hilbert space is obtained. Strongly continuous one-

Mapping with confidence; delineating seagrass habitats using Unoccupied Aerial Systems (UAS)
Remote Sensing in Ecology and Conservation, 2019 There is growing interest in the use of Unoccupied Aerial Systems (UAS) for mapping and monitoring of seagrass habitats. UAS provide flexibility with timing of imagery capture, are relatively inexpensive, and obtain very high spatial resolution imagery ...
