The commutation principle of Ramirez et al. (SIAM J Optim 23:687–694, 2013) proved in the setting of Euclidean Jordan algebras says that when the sum of a real valued function h and a spectral function $$\Phi $$ is minimized/maximized over a spectr

Given a linear map T on a Euclidean Jordan algebra of rank n, we consider the set of all nonnegative vectors q in R n with decreasing components that satisfy the pointwise weak-majorization inequal...

In a Euclidean Jordan algebra V of rank n, an element x is said to be majorized by an element y, symbolically x ≺ y , if the corresponding eigenvalue vector λ ( x ) is majorized by λ ( y ) in R n . In this article, we describe pointwise majorizat

In a Euclidean Jordan algebra V of rank n which carries the trace inner product, to each element x we associate the eigenvalue vector λ ( x ) whose components are the eigenvalues of x written in the decreasing order. For any p ∈ [ 1 , ∞ ] , we d

In the setting of a Euclidean Jordan algebra V with symmetric cone $$V_+$$ , corresponding to a linear transformation M, a ‘weight vector’ $$w\in V_+$$ , and a $$q\in V$$ , we consider the weighted linear complementarity problem wLCP(M, w, q) and

Let V be a Euclidean Jordan algebra of rank n. A set E in V is said to be a spectral set if there exists a permutation invariant set Q in R n such that E = λ − 1 ( Q ) , where λ : V → R n is the eigenvalue map that takes x ∈ V to λ ( x ) (th

Motivated by Horn's log-majorization (singular value) inequality $s(AB)\underset{log}{\prec} s(A)*s(B)$ and the related weak-majorization inequality $s(AB)\underset{w}{\prec} s(A)*s(B)$ for square complex matrices, we consider their Hermitian analogs
