Inequalities related to Bourin and Heinz means with a complex parameter
(Academic Press Inc Elsevier Science, 2015-06-15)
A conjecture posed by S. Hayajneh and F. Kittaneh claims that given A, B positive matrices, 0≤t≤1, and any unitarily invariant norm the following inequality holds{triple vertical-rule fence}AtB1-t+BtA1-t{triple vertical-rule ...

Whose rules? Whose power? The Global South and the possibility to shape international peacekeeping norms through leadership appointments
(2022)
International organisations reflect global power configurations and as such, are deemed to reproduce global inequalities. Nevertheless, they also represent opportunities for the Global South to challenge the global ...
Some operator inequalities for unitary invariant norms
(Unión Matemática Argentina, 2005-12)
Let L(H) be the algebra of bounded operators on a complex separable Hilbert space H. Let N be a unitary invariant norm defined on a norm ideal I ⊆ L(H)$. Given two positive invertible operators P, Q ∈ L(H) and k ∈ (-2,2], ...

Brazilian standardised norms for a set of pictures are comparable with those obtained internationally
(Academia Brasileira de Neurologia - ABNEURO, 2003-12-01)
Snodgrass & Vanderwart (1980) standardized a set of 260 pictures in the USA for use in studies of cognitive processes that employ pictured objects as laboratory analogues of object themselves. Since then similar norms for ...
Geometric Interpolation in Symmetrically-normed Ideals
(Elsevier, 2008-12)
The aim of this work is to apply the complex interpolation method to norms of n-tuples of operators in a symmetrically-normed ideal J contained in B(H) defined by a symmetric norming function (s.n.f.). The norms considered ...

On the complexity of computing estimates of condition measures of a conic linear system
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 2003)
Condition numbers based on the "distance to ill-posedness" rho(d) have been shown to play a crucial role in the theoretical complexity of solving convex optimization models. In this paper, we present two algorithms and ...
