Siklos spacetime represents exact gravitational waves propa�gating on the anti-de-Sitter universe with negative cosmological constant and it is conformally related to pp-wave spacetime. The object of this paper is to investigate the curvature restricted geometric structures ad�mitting by the Siklos spacetime and it is shown that such spacetime is E...

... Also if α = 0, then the m-quasi-Einstein manifold turns into a Ricci simple manifold. We note that Morris-Thorne spacetime [103] and Gödel spacetime [28] are Ricci simple manifolds, Robertson-Walker spacetime [26] and Siklos spacetime [29] are quasi-Einstein manifolds, Kantowski-Sachs spacetime [84] and Som-Raychaudhuri spacetime [25] are 2-quasi Einstein manifolds and Kaigorodov spacetime [29] is an Einstein manifold. For curvature properties of Robinson-Trautman metric, Melvin magnetic metric and generalized pp-wave metric, etc., we refer the reader to see [30,[104][105][106]. ...
