Anisotropic interpolation error estimate for arbitrary quadrilateral isoparametric elements
Gabriel Monzón
The aim of this paper is to show that, for any , the -anisotropic interpolation error estimate holds on quadrilateral isoparametric elements verifying th…
An extension of the Pólya--Szegö operator inequality
D. T. Hoa, M. S. Moslehian, C. Conde +1
We extend an operator Pólya--Szegö type inequality involving the operator geometric mean to any arbitrary operator mean under some mild conditions. Utilizing the Mond--Pečarić meth…
Orthogonality and parallelism of operators on various Banach spaces
T. Bottazzi, C. Conde, M. S. Moslehian +2
We present some properties of orthogonality and relate them with support disjoint and norm inequalities in p Schatten ideals. In addition, we investigate the problem of characteriz…
Thermal expansion in nanoresonators
Agustín Mancardo Viotti, Alejandro G. Monastra, Mariano F. Moreno +1
Inspired by some recent experiments and numerical works related to nanoresonators, we perform classical molecular dynamics simulations to investigate the thermal expansion and the…
Frequency thermal response and cooling performance in a microscopic system with a time-dependent perturbation
N. Beraha, A. Soba, M. F. Carusela
Following the nonequilibrium Green's function formalism we study the thermal transport in a composite chain subject to a time-dependent perturbation. The system is formed by two fi…
A Grüss type operator inequality
Tamara Bottazzi, Cristian Conde
In [P. Renaud, "A matrix formulation of Grüss inequality", Linear Algebra Appl. 335 (2001), 95--100] it was proved an operator inequality involving the usual trace functional. In t…
