From positive to accretive matrices
نویسندگان
چکیده
The main goal of this paper is to discuss the recent advancements matrix means from positive matrices accretive in a more general setting. In particular, we present form governing well established definition geometric mean, then define arbitrary and functional calculus for matrices. Applications new discussion involve generalizations known inequalities setting that This includes arithmetic-harmonic mean comparisons, monotonicity means, Ando’s inequality, Choi’s Ando–Zhan subadditive inequality much more.

Singular value inequalities for positive semidefinite matrices
In this note, we obtain some singular values inequalities for positive semidefinite matrices by using block matrix technique. Our results are similar to some inequalities shown by Bhatia and Kittaneh in [Linear Algebra Appl. 308 (2000) 203-211] and [Linear Algebra Appl. 428 (2008) 2177-2191].
متن کاملElimination techniques: from extrapolation to totally positive matrices and CAGD
In this survey, we will show some connections between several mathematical problems such as extrapolation, linear systems, totally positive matrices and computer-aided geometric design, with elimination techniques as the common tool to deal with all of them. c © 2000 Elsevier Science B.V.

متن کاملSymmetric Positive-Definite Matrices: From Geometry to Applications and Visualization
In many engineering applications that use tensor analysis, such as tensor imaging, the underlying tensors have the characteristic of being positive definite. It might therefore be more appropriate to use techniques specially adapted to such tensors. We will describe the geometry and calculus on the Riemannian symmetric space of positive-definite tensors. First, we will explain why the geometry,...
متن کاملNearly positive matrices
Nearly positive matrices are nonnegative matrices which, when premultiplied by orthogonal matrices as close to the identity as one wishes, become positive. In other words, all columns of a nearly positive matrix are mapped simultaneously to the interior of the nonnegative cone by mutiplication by a sequence of orthogonal matrices converging to the identity. In this paper, nearly positive matric...
متن کاملA note on positive deniteness and stability of interval matrices
It is proved that by using bounds of eigenvalues of an interval matrix, someconditions for checking positive deniteness and stability of interval matricescan be presented. These conditions have been proved previously with variousmethods and now we provide some new proofs for them with a unity method.Furthermore we introduce a new necessary and sucient condition for checkingstability of interval...
