我们在反德西特和德西特背景时空中构造了不同的中性黑褶解，其中宇宙常数被认为远小于视界大小。这包括一类视界为奇球与横球乘积的黑褶，并对其热力学稳定性进行了研究。此外，我们还展示了一个特定的例子，在这个例子中，相同的黑褶解可以描述不同的极限黑洞时空，从而说明了黑褶方法的几何特征。此外，我们证明了高维Kerr-(Anti)-de Sitter黑洞允许在考虑的相同限制下的超旋转状态，并证明了这是由pancaked blackfold几何正确描述的。我们也给出了在这些背景下饱和刚性定理的可能性的证据。
We construct different neutral blackfold solutions in Anti-de Sitter and de Sitter background spacetimes in the limit where the cosmological constant is taken to be much smaller than the horizon size. This includes a class of blackfolds with horizons that are products of odd-spheres times a transverse sphere, for which the thermodynamic stability is also studied. Moreover, we exhibit a specific case in which the same blackfold solution can describe different limiting black hole spacetimes therefore illustrating the geometric character of the blackfold approach. Furthermore, we show that the higher-dimensional Kerr-(Anti)-de Sitter black hole allows for ultraspinning regimes in the same limit under consideration and demonstrate that this is correctly described by a pancaked blackfold geometry. We also give evidence for the possibility of saturating the rigidity theorem in these backgrounds.
