Minimal hermitian matrices with fixed entries outside the diagonal [PDF]

, 2008
We survey some results concerning the problem of finding the complex hermitian matrix or matrices of least supremum norm with variable diagonal. Some qualitative general results are given and more specific descriptions are shown for the 3 x 3 case.

Coupling of Er3+ ions and Plasmonic Modes in Vertical Nanocavities for Spectral Broadening in Telecom Bands

Advanced Materials Technologies, EarlyView.
Left: Illustration of the glass & nanostructures system and the NIR emission at 1.5 µm, where the colored spheres represent the Er3+ ions within the doped glass. Right: Representation of the Stark splitting of the 4I13/2 and 4I15/2 manifolds of the Er3+, illustrating how the plasmonic modes facilitate the emission from the broader Stark manifold ...

Exponential instability in the fractional Calderón problem [PDF]

, 2017
In this paper we prove the exponential instability of the fractional Calderón problem and thus prove the optimality of the logarithmic stability estimate from Rüland and Salo (2017 arXiv:1708.06294).

Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves

Astronomische Nachrichten, EarlyView.
ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).

Commutators of multilinear Calderón-Zygmund operators with kernels of Dini's type and applications

Journal of Mathematical Inequalities, 2019
. Let T be a multilinear Calder´on-Zygmund operator of type ω with ω ( t ) being non- decreasing and satisfying a kind of Dini’s type condition. Let T Π (cid:2) b be the iterated commutators of T with BMO functions. The weighted strong and weak L ( log L

Lifting properties in operator ranges [PDF]

, 2009
Given a bounded positive linear operator A on a Hilbert space H we consider the semi-Hilbertian space (H, _A), where _A =. On the other hand, we consider the operator range R(A^1/2) with its canonical Hilbertian structure, denoted by R(A^1/2).

A Network Analysis of Alexithymia, Interoception, Empathy, Self‐Awareness and Psychopathological Symptoms in Young People With Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Autism Spectrum Disorder (ASD) is associated with altered interoception, empathy, self‐awareness, and alexithymia. However, limited research has been conducted to investigate the interrelationships of these constructs with psychopathological symptoms.
