Abstract: (arXiv)
The initial data sets for the five-dimensional Einstein equation have been examined. The system is designed such that the black hole (S3\simeq S^3) or the black ring (S2×S1\simeq S^2\times S^1) can be found. We have found that the typical length of the horizon can become arbitrarily large but the area of characteristic closed two-dimensional submanifold of the horizon is bounded above by the typical mass scale. We conjecture that the isoperimetric inequality for black holes in nn-dimensional space is given by Vn2GMV_{n-2} \lesssim GM, where Vn2V_{n-2} denotes the volume of typical closed (n2)(n-2)-section of the horizon and MM is typical mass scale, rather than C(GM)1/(n2)C\lesssim (GM)^{1/(n-2)} in terms of the hoop length CC, which holds only when n=3n=3.
