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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

We present weighted covariant derivatives and wave operators for perturbations of certain algebraically special Einstein spacetimes in arbitrary dimensions, under which the Teukolsky and related equations become weighted ...
