论文摘要
获得了相对论恒星的扰动构型的波动划分关系。经典应力张量的随机波动包括相对论之星的物质含量（完美的流体），充当了描述系统的经典Einstien-langevin方程中的来源。我们讨论了应力张量的这些波动的线性响应，并从第一原理发展出波动的衰落关系。因此，提出了在时空度量和物质含量方面进行系统浴的分离，以研究相对论恒星的平衡和非平衡统计特性。这不是与标量场或量子应力张量及其波动相关的或相关的，就像半经典重力一样。
A fluctuation-dissipation relation for perturbed configuration of a relativistic star is obtained. The stochastic fluctuations of the classical stress tensor comprising the matter content ( a perfect fluid) of the relativistic star, act as the source in a classical Einstien-Langevin equation describing the system. We discuss the linear response of these fluctuations of the stress tensor and develop a fluctuation-dissipation relation from the first principles. Thus a system-bath separation in terms of spacetime metric and matter content is proposed, to study equilibrium and non equilibrium statistical properties for a relativistic star. This is not derived from or related to the scalar fields or quantum stress tensors and their fluctuations, as is usually the case for semiclassical stochastic gravity.
