Penrose不等式的Jang方程解法

A Jang Equation Approach to the Penrose Inequality

Hubert L. Bray, Marcus A. Khuri

摘要:

我们引入了一个广义的Jang方程,它是为满足支配能量条件的时空的渐近平坦空间-类超曲面中的Penrose不等式的一般情形而设计的.在球对称Cauchy数据的特殊情况下,建立了相应的存在性和正则性结果,并应用于这类数据给出了一般Penrose不等式的一个新的证明.当适当地与反中曲率流耦合时,在非球面情形下,相应的方程组的类似存在性和正则性结果将给出完整的彭罗斯猜想的证明。因此,它仍然是一个重要的和具有挑战性的开放的问题,以确定该系统是否确实承认所需的解决方案。

英文摘要:

We introduce a generalized version of the Jang equation, designed for the general case of the Penrose Inequality in the setting of an asymptotically flat space-like hypersurface of a spacetime satisfying the dominat energy condition. The appropriate existence and regularity results are established in the special case of spherically symmetric Cauchy data, and are applied to give a new proof of the general Penrose Inequality for these data sets. When appropriately coupled with an inverse mean curvature flow, analogous existence and regularity results for the associated system of equations in the nonspherical setting would yield a proof of the full Penrose Conjecture. Thus it remains as an important and challenging open problem to determine whether this system does indeed admit the desired solutions.
