Normal holonomy of orbits and Veronese submanifolds
(2015)
It was conjectured, twenty years ago, the following result that would generalize the so-called rank rigidity theorem for homogeneous Euclidean submanifolds: let Mn, n ≥ 2, be a full and irreducible homogeneous submanifold ...
A statistical study of heterogeneous nucleation of ice by molecular dynamics
(2015)
We studied the stochastic nature of heterogeneous nucleation of supercooled liquid water by molecular dynamics simulations. The systems were composed of 768 molecules; M of them had their positions restricted forming a ...
Time and band limiting for matrix valued functions, an example
(2015)
The main purpose of this paper is to extend to a situation involving matrix valued orthogonal polynomials and spherical functions, a result that traces its origin and its importance to work of Claude Shannon in laying the ...
Advanced LIGO
(2015)
The Advanced LIGO gravitational wave detectors are second-generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA, USA. The two instruments are identical in design, and ...
Una experiencia vivida en aula : enseñar y aprender a trabajar con estadística desde una perspectiva crítica
(2015)
En este artículo se presenta una descripción de una experiencia escolar realizada en una escuela secundaria de una localidad de la provincia de Córdoba donde la segunda autora se desempeña como profesora de matemática. La ...
Bounds for axially symmetric linear perturbations for the extreme Kerr black hole
(2015)
We obtain remarkably simple integral bounds for axially symmetric linear perturbations for the extreme Kerr black hole in terms of conserved energies. From these estimates we deduce pointwise bounds for the perturbations ...
Curvature flows for almost-hermitian Lie groups
(2015)
We study curvature flows in the locally homogeneous case (e.g. compact quotients of Lie groups, solvmanifolds, nilmanifolds) in a unified way, by considering a generic flow under just a few natural conditions on the broad ...
Invariants of complex structures on nilmanifolds
(2015)
Let (N, J) be a simply connected 2n-dimensional nilpotent Lie group endowed with an invariant complex structure. We define a left invariant Riemannian metric on N compatible with J to be minimal, if it minimizes the norm ...
Calibration method for confocal X-ray microanalysis with polychromatic excitation
(2015)
To apply the fundamental parameters method at the confocal setup the knowledge of the sensitivity of the spectrometer is required which depends on the characteristics of two X-ray lenses: one in the excitation channel and ...
Properties of NiMnGa alloys ultra rapidly solidified by suction casting
(2015)
Ni2MnGa alloys are obtained by suction casting in water chilled cylindrical copper moulds 50 mm long and 1-4 mm in diameter; the microstructure and the magnetic properties are then investigated as functions of the cylinder ...
