Estructuras Killing-Yano invariantes en variedades homogéneas
(2018-03)
Estudiamos 2-formas de Killing-Yano invariantes a izquierda sobre grupos de Lie, o equivalentemente, sobre álgebras de Lie. Más particularmente, clasificamos las álgebras de Lie de dimensión 4 que admitan tales estructuras, ...
Invariant solutions to the conformal Killing–Yano equation on Lie groups
(2015)
We search for invariant solutions of the conformal Killing–Yano equation on Lie groups equipped with left invariant Riemannian metrics, focusing on 2-forms. We show that when the Lie group is compact equipped with a ...
Killing-Yano 2-forms on homogeneous spaces
(Springer International Publishing, 2018-12)
Riemannian manifolds carrying skew (1, 1)-tensors satisfying the Killing-Yano equation are natural generalizations of nearly Kähler manifolds. In this article we investigate the existence of invariant solutions to the ...
Invariant solutions to the conformal Killing-Yano equation on Lie groups
(Elsevier Science, 2015-08)
We search for invariant solutions of the conformal Killing-Yano equation on Lie groups equipped with left invariant Riemannian metrics, focusing on 2-forms. We show that when the Lie group is compact equipped with a ...
The Killing–Yano equation on Lie groups
(IOP Publishing, 2012-02)
In this paper we study 2-forms which are solutions of the Killing–Yano equation on Lie groups endowed with a left invariant metric having various curvature properties. We prove a general result for 2-step nilpotent Lie ...
Killing–Yano 2-forms on 2-step nilpotent Lie groups
(Springer, 2021-06-01)
In this article we show that the only 2-step nilpotent Lie groups which carry a non-degenerate left invariant Killing–Yano 2-form are the complex Lie groups. In the case of 2-step nilpotent complex Lie groups arising from ...
Conformal Killing–Yano 2-forms
(Elsevier Science, 2018-06)
Riemannian manifolds carrying 2-forms satisfying the Killing-Yano equation and the conformal Killing-Yano equation are natural generalizations of nearly Kähler and Sasakian manifolds. In this article we exhibit new solutions ...
Hazards and critical control points in Brazilian seafood dish preparation
(Food Control, 2007)
There are many concerns about the sanitation practices used in the preparation of the foods and the occurrence of the gastrointestinal
illness affecting mainly tourists who come to Salvador, Bahia, Brazil, on vacation is ...
Hidden symmetries and supergravity solutions
(American Institute Of Physics, 2012-04)
The role of Killing and Killing-Yano tensors for studying the geodesic motion of the particle and the superparticle in a curved background is reviewed. Additionally, the Papadopoulos list [G. Papadopoulos, Class. Quantum ...
