Symposium on Black Holes and Relativistic Stars, University of Chicago, Dec.14-15, 1996

广义相对论中的黑洞和相对论恒星理论在20世纪60年代中期到70年代中期得到了很大的发展。然而，近年来，由于一些独立的研究方向，这一领域出现了许多重要的新进展。这些研究方向包括：(1)通过数值技术研究黑洞碰撞细节的“大挑战”相关研究。(2)分析了LIGO和其他引力波探测器探测黑洞和中子星详细特性的潜在能力。(3)来自哈勃太空望远镜和其他观测的黑洞存在的新证据。(4)对黑洞内部结构的理论分析表明，在黑洞的理想模型中出现的“内视界”可能会成为现实黑洞中相对温和类型的零奇点。(5)进一步分析二维理论中的霍金效应及其类似物，特别是关于黑洞蒸发过程中状态纯度是否恢复的问题。(6)在经典广义相对论、半经典引力、量子引力和弦理论的背景下，对黑洞熵的性质和起源进行了大量研究。为了讨论这些最近的发展，将于1996年12月14日和15日的周末在芝加哥大学校园举行一次关于“黑洞和相对论恒星”的研讨会（就在德克萨斯研讨会之前，也将在芝加哥举行）。研讨会将包括为期两天的全体演讲，每次大约一小时，由V. Ferrari、J. Friedman、J. Hartle、S.W. Hawking、W. Israel、R. Penrose、M. Rees、R. Sorkin、S. Teukolsky、K. Thorne、R. Wald和E. Witten主讲。研讨会将以纪念S.钱德拉塞卡为主题。

The theory of black holes and relativistic stars in general relativity was largely developed during the period from the mid 1960's to the mid 1970's. However, in recent years many important, new developments in this area have occurred as a result of a number of independent lines of research. These lines of investigation include: (1) Research associated with the `Grand Challenge` effort to study the details of black hole collisions by numerical techniques. (2) Analyses of the potential ability of LIGO and other gravitational wave detectors to probe detailed properties of black holes and neutron stars. (3) New evidence from the Hubble Space Telescope and other observations for the presence of black holes. (4) Theoretical analyses of the internal structure of black holes, which suggest that the `inner horizon` occurring in idealized models of black holes may become a null singularity of a relatively mild type for realistic black holes. (5) Further analyses of the Hawking effect and its analog in 2-dimensional theories, particularly with regard to the issue of whether purity of states is restored in the black hole evaporation process. (6) Numerous investigations in the contexts of classical general relativity, semiclassical gravity, quantum gravity, and string theory regarding the nature and origin of black hole entropy. To discuss these recent developments, a Symposium on `Black Holes and Relativistic Stars` will be held on the University of Chicago Campus on the weekend of December 14 and 15, 1996 (just prior to the Texas Symposium, also to be held in Chicago). The Symposium will consist entirely of two days of plenary lectures of approximately one hour duration each by V. Ferrari, J. Friedman, J. Hartle, S.W. Hawking, W. Israel, R. Penrose, M. Rees, R. Sorkin, S. Teukolsky, K. Thorne, R. Wald, and E. Witten. The Symposium will be dedicated to the memory of S. Chandrasekhar.
