论文摘要
标准的延展超级$ p $ branes的标量费用不是独立参数，而是由brane张力和页面费用确定。可以将此功能追溯到四维爱因斯坦 - 标准重力中的无头发定理，这意味着具有独立标量电荷的更通用的解决方案可能具有裸露的奇异性。由于奇异的麸皮也作为不稳定的速晶和/或brane-antibrane系统的初步经典对应物，因此值得详细研究具有独立标量电荷的麸皮。在这里，我们研究了与四维重力的Fisher-Janis-Newman-Winicour溶液相关的单数麸皮。在Condimension第三的情况下，我们还构建了具有Zipoy-Voorhees型涂抹参数的奇异晶体。可以预期，在弦理论中，这种麸皮不会超对称。我们在II型理论的NS5-贿赂的特殊情况下证明了这一点。我们分析了新溶液的大地测量和测试标量扰动，重点是经典奇异性的量子愈合。
Standard dilatonic supergravity $p$-branes have scalar charges that are not independent parameters, but are determined by the brane tension and Page charges. This feature can be traced to the no-hair theorem in the four-dimensional Einstein-scalar gravity, implying that more general solutions with independent scalar charges can have naked singularities. Since singular branes are also of interest as tentative classical counterparts of unstable tachyonic branes and/or brane-antibrane systems, it is worth investigating branes with independent scalar charges in more detail. Here we study singular branes associated with the Fisher-Janis-Newman-Winicour solution of four-dimensional gravity. In the case of codimension three, we also construct singular branes endowed with a Zipoy-Voorhees-type oblateness parameter. It is expected that such branes will not be supersymmetric in the string theory. We demonstrate this in the special case of NS5-branes of type II theory. We analyze geodesics and test scalar perturbations of new solutions focusing on possible quantum healing of classical singularities.
