我们考虑一类新的Weyl-共形不变p-膜理论，它描述了任何奇数世界体积维数的内在类光膜，因此首字母缩写为WILL-branes（Weyl-不变类光膜）。我们讨论了一些详细的WILL膜动力学显着不同于普通的Nambu-Goto膜动力学的属性。我们提供了WILL-膜的显式解（即，p=2）运动方程在任意D=4球对称静态引力背景下，以及在Kaluza-Klein背景下感兴趣的乘积空间中。在第一种情况下，我们发现，WILL膜实现了相应的黑洞解决方案的事件视界，从而提供了一个明确的动力学实现的膜范式在黑洞物理。在第二个“卡鲁扎-克莱因”的上下文中，我们找到了描述WILL膜的解，这些膜包裹在内部（紧致）维周围，并作为一个整体在非紧致（时空）维中以光速运动。
We consider a novel class of Weyl-conformally invariant p-brane theories which describe intrinsically light-like branes for any odd world-volume dimension, hence the acronym WILL-branes (Weyl-Invariant Light-Like branes). We discuss in some detail the properties of WILL-brane dynamics which significantly differs from ordinary Nambu-Goto brane dynamics. We provide explicit solutions of WILL-membrane (i.e., p=2) equations of motion in arbitrary D=4 spherically symmetric static gravitational backgrounds, as well as in product spaces of interest in Kaluza-Klein context. In the first case we find that the WILL-membrane materializes the event horizon of the corresponding black hole solutions, thus providing an explicit dynamical realization of the membrane paradigm in black hole physics. In the second "Kaluza-Klein" context we find solutions describing WILL-branes wrapped around the internal (compact) dimensions and moving as a whole with the speed of light in the non-compact (space-time) dimensions.
