标题： On the formation of black holes in non-symmetric gravity

摘要： 最近有建议认为非对称引力理论（NGT）不存在黑洞。 在这里，我们研究NGT的线性版本。 我们发现，即使具有球对称性，度规的斜部分通常是非静态的。 此外，如果初始的斜场是正则的，它将在所有地方保持正则，特别是在视界处。 因此，在完全非线性理论中，如果初始的斜场足够小，预期会形成黑洞。 显示英文摘要

摘要： It has been recently suggested that the Non-symmetric Gravitational Theory (NGT) is free of black holes. Here, we study the linear version of NGT. We find that even with spherical symmetry the skew part of the metric is generally non-static. In addition, if the skew field is initially regular, it will remain regular everywhere and, in particular, at the horizon. Therefore, in the fully-nonlinear theory, if the initial skew-field is sufficiently small, the formation of a black hole is to be anticipated.
