摘要
对于一个黑洞视界外部的观察者来说,黑洞视界表面的动力学性质与一个流体膜的表现非常相似.本文将膜范式推广到了Gauss-Bonnet引力,推导了视界表面的应力张量,计算了流体的输运系数,最后计算了Gauss-Bonnet引力在具体度规下的流体输运系数的修正.期望在其他的修正引力中黑洞视界有着同样的流体性质.
To an outside observer,a black hole's event horizon behavesexactly like a dynamical fluid membrane.We extend this membrane paradigm to black holes in GaussBonnet modified theories of gravity.We derive the stress tensor and various transport coefficients of the fluid and evaluate the transport coefficients for a static geometry.We reckon on what theories of gravity admit horizon with fluid properties.
