Generalized convexity of spectral functions on Euclidean Jordan algebras
Juyoung Jeong
This paper investigates transfer principles for generalized convexity of spectral functions on Euclidean Jordan algebras. A spectral function is induced by the eigenvalue map and a…
Minimal polynomials, scaled Jordan frames, and Schur-type majorization in hyperbolic systems
M. Seetharama Gowda, Juyoung Jeong, Sudheer Shukla
Corresponding to a hyperbolic system , where is a real finite-dimensional vector space and is a hyperbolic polynomial of degree in the direction , we cons…
Geometric commutation principle for weakly spectral sets in Euclidean Jordan algebras
Juyoung Jeong
A geometric commutation principle in Euclidean Jordan algebra, recently proved by Gowda, says that, for any spectral set in a Euclidean Jordan algebra and , st…
Commutation principles for nonsmooth variational problems on Euclidean Jordan algebras
Juyoung Jeong, David Sossa
The commutation principle proved by Ramírez, Seeger, and Sossa (SIAM J Optim 23:687-694, 2013) in the setting of Euclidean Jordan algebras says that for a Fréchet differentiable fu…
Some log and weak majorization inequalities in Euclidean Jordan algebras
Jiyuan Tao, Juyoung Jeong, Muddappa Gowda
Motivated by Horn's log-majorization (singular value) inequality and the related weak-majorization inequality $s(AB)\underset{w}{\prec} s(A)*…
Commutation principles in Euclidean Jordan algebras and normal decomposition systems
M. Seetharama Gowda, Juyoung Jeong
The commutation principle of Ramirez, Seeger, and Sossa \cite{ramirez-seeger-sossa} proved in the setting of Euclidean Jordan algebras says that when the sum of a Fréchet different…
