Completely positive mappings and mean matrices
Some functions f : R+ → R+ induce mean of positive numbers and the matrix monotonicity gives a possibility for means of positive definite matrices. Moreover, such a function f can define a linear mapping (JfD) −1 : Mn → Mn on matrices (which is basic in the constructions of monotone metrics). The present subject is to check the complete positivity of (JfD) −1 in the case of a few concrete funct...
متن کاملMatrices with High Completely Positive Semidefinite Rank
A real symmetric matrix M is completely positive semidefinite if it admits a Gram representation by positive semidefinite matrices (of any size d). The smallest such d is called the completely positive semidefinite rank of M , and it is an open question whether there exists an upper bound on this number as a function of the matrix size. We show that if such an upper bound exists, it has to be a...
متن کاملSeparating doubly nonnegative and completely positive matrices
The cone of Completely Positive (CP) matrices can be used to exactly formulate a variety of NP-Hard optimization problems. A tractable relaxation for CP matrices is provided by the cone of Doubly Nonnegative (DNN) matrices; that is, matrices that are both positive semidefinite and componentwise nonnegative. A natural problem in the optimization setting is then to separate a given DNN but non-CP...
متن کاملA note on “ 5 × 5 Completely positive matrices ”
In their paper “5×5 Completely positive matrices,” Berman and Xu [BX04] attempt to characterize which 5× 5 doubly nonnegative matrices are also completely positive. Most of the analysis in [BX04] concerns a doubly nonnegative matrix A that has at least one off-diagonal zero component. To handle the case where A is componentwise strictly positive, Berman and Xu utilize an “edge-deletion” transfo...
متن کاملNotes on Simplification of Matrices
These notes discuss how to “simplify” an (n × n) matrix. From the point of view of the larger context of the course, the goal is to have a way to compute e for a given matrix A, which is useful in solving linear ODEs. This is a preliminary version. If you have any comments or corrections, even very minor ones, please let me know. Let us note that the definition of exponentials of matrices and t...
