The Singular Values of the GOE [PDF]

open access: yes, 2015
As a unifying framework for examining several properties that nominally involve eigenvalues, we present a particular structure of the singular values of the Gaussian orthogonal ensemble (GOE): the even-location singular values are distributed as the ...

A Novel Neural Network Framework for Automatic Modulation Classification via Hankelization-Based Signal Transformation

open access: yesApplied Sciences
Automatic modulation classification (AMC) is a fundamental technique in wireless communication systems, as it enables the identification of modulation schemes at the receiver without prior knowledge, thereby promoting efficient spectrum utilization ...

Properties of singular points in a special case of orthorhombic media

open access: yesГеофизический журнал, 2023
The position of singular lines for orthorhombic (ORT) media with fixed diagonal elements of the elasticity matrix cij, i=1…6 is studied under the condition that c11, c22, c33>c66>c44>c55.

Singular values of the Dirac operator at nonzero density

open access: yes, 2012
At nonzero density the eigenvalues of the Dirac operator move into the complex plane, while its singular values remain real and nonnegative. In QCD-like theories, the singular-value spectrum carries information on the diquark (or pionic) condensate.

Tracial and majorisation Heinz mean-type inequalities for matrices

open access: yesJournal of Inequalities and Applications, 2016
The Heinz mean for every nonnegative real numbers a, b and every 0 ≤ ν ≤ 1 $0\le\nu\le1$ is H ν ( a , b ) = a ν b 1 − ν + a 1 − ν b ν 2 $H_{\nu}(a , b)=\frac{a^{\nu}b^{1-\nu} +a^{1-\nu}b^{\nu}}{2}$ .
