회고 및 전망 (回顧/展望 OVERVIEWS & PERSPECTIVES)
“Einstein's Path to General Relativity”
Mu-In Park* (Sogang U)
Abstract: We know Einstein's general relativity (GR) as its final form in 1915 but it is the result of 10 years trials and errors even for the great physicist, may be the greatest after Isaac Newton. In the "first" part of
this talk, we will briefly sketch his 10 years "zigzag" path toward GR from the "physical" point of views. We would get some good lessons from this retrospection.
“Modifications of general relativity”
Hyeong-Chan Kim (Korea Nat’l U of Transportation)
Abstract: There are various modifications of general relativity. We summarize some of them in terms of the motivations and methodology.
“Spacetime solutions and their understandings”
Sung-Won Kim (Ewha Womans U) and Gungwon Kang (KISTI)
Abstract: We briefly review some of main spacetime solutions and their understandings discovered for the last 100 years of general relativity. It includes Schwarzschild metric and Kruskal’s work, Stellar collapse and formation of black holes, Spinning BH, Stability, BH no hair theorem, etc..
“Some exact solutions in (2+2) Hamiltonian Reduction”
Seung Hun Oh (Konkuk U)
Abstract: In this talk some implications of (2+2) Hamiltonian reduction will be shown. It includes how this reduction formalism can reproduce the canonical quantization of the Einstein-Rosen waves done by K. Kuchar, and also some well-known solutions to the Einstein's equation will be derived in the frame of (2+2) reduction.
“Dark energy and dark matter”
Hyung Won Lee (Inje U);
Abstract: Einstein's cosmological constant was introduced to obtain stable and static solution for Einstein field equations by Einstein. It was abandoned after Hubble's discovery for expnading and dynamic cosmology. However, precise astrophysical observation requires again the cosmological constant at least to explain the accelerated expansion. Currently, most astrophysicists and cosmologists agree about the existence of dark energy and dark matter to explain observational data. The physical principle for these two dark components of the universe is still unknown. In this presentation, I will review the current status of dark energy and dark matter research.
“Testing general relativity experimentally: Equivalence Principle Tests”
Ki Young Choi (Seoul Nat’l U)
Abstract: I will review the "Tests of the Equivalence Principle and the Universality of Free Fall" historically. They will be parameterized by the Eötvös parameter which is indicated the difference acceleration of two different test masses toward the source masses.
“Motion of binaries in general relativity and computation of gravitational waves (GWs): Post-Newtonian (PN) approximations and other implementation methods”
Dong-Hoon Kim (Ewha Womans U) and Hee-Suk Cho (KISTI)
Abstract: In this talk we will give brief reviews on typical methods to compute GWs from binaries, depending on their mass ratios: (i) PN approximations for comparable mass ratios, (ii) point-particle and semi-relativistic approximations for extreme mass ratios. In conjunction with this, we will also review briefly the search efforts of GW signals and the parameter estimation in GW data analysis.

Towards the quantum gravity:
“Information loss problem and Euclidean path integral approach”
Dong-han Yeom (National Taiwan U)
Abstract: I first review the current status of the information loss problem. In order to resolve the paradox, we need to investigate non-perturbative effects; the Euclidean path integral approach will be the highway to this direction. I show the conceptual way how to understand the information loss problem by using the Euclidean path integral. Finally, I illustrate some concrete examples that realize this idea.
“General Relativity vs. Emergent Gravity”
Hyun Seok Yang (Sogang U)
Abstract: I recapitulate recent developments on emergent gravity in string theory and highlight significant differences between emergent gravity and general relativity. I emphasize why noncommutative spacetime takes a superb mission for the backround-independent formulation of quantum gravity.

INVITED TALKS
“Gravitational wave background from astrophysical sources”
Zong-Hong Zhu (Beijing Normal U)
Abstract: We report a comprehensive study on the gravitational wave (GW) background from compact binary
coalescences. We consider in our calculations newly available observation-based neutron star and black hole
mass distributions and complete analytical waveforms that include post-Newtonian amplitude corrections. We
also explore the parameter space required for detection by advanced and third generation interferometric GW
detectors.

I give a short historical background that led to the discovery of black holes, and the current status of our knowledge about the cosmic evolution of massive black holes and how important they are to understand the cosmic history.
“General relativity in Japan: a historical perspective“
Misao Sasaki (YITP)
Abstract: TBA
“100 Years after Einstein: A Personal Perspective”
Yongmin Cho (Konkuk U)
Abstract: Theoretical developments of Einstein’s theory during the last 100 years are reviewed, with the emphasis on the Abelian decomposition and Abelian dominance of Einstein’s theory which suggests the spin-one graviton.
“On non-minimally derivative coupling”
Yunqui Gong (HUST)
Abstract: Horndeski theory is the most general scalar-tensor theory that gives at most second order equation of motion, one of the special case is the coupling between the kinetic term of the scalar field and Einstein tensor, this non-minimally derivative coupling successfully implements slow-roll inflation. In this talk, I will first talk about the parameterized post-Newtonian parameters in this theory, and then talk about the scalar and tensor spectral indices up to second order in slow-roll parameters, finally I will talk about the phase-space analysis and the thermodynamics of this theory.
“Variations of fundamental constants from multidimensional gravity”
Kirill Bronnikov (VNIIMS)
Abstract: The observational status of possible variations of different fundamental constants is outlined. The recently reported large-scale spatial variations of the fine structure constant α are discussed, along with their explanations suggested by different authors. We try to explain these variations in the framework of curvature-nonlinear multidimensional gravity. Under the reasonable assumption of slow changes of all quantities as compared with the Planck scale, the original theory reduces to a multiscalar field theory in four dimensions. On this basis, we consider different variants of isotropic cosmological models in both the Einstein and Jordan conformal frames. One of the models turns out to be equally viable in both frames, but in Jordan's frame the model predicts simultaneous variations of α and the gravitational constant G, equal in magnitude. Large-scale small inhomogeneous perturbations of these models allow for explaining the observed spatial distribution of α values.
“High-energy Astrophysics with neutron stars and black holes: An observational point of view”
Hongjun An (Stanford U.)
Abstract: Strong general relativistic (GR) effects exist near compact objects such as neutron stars and black holes. These effects are visible in the observed electromagnetic waves emitted by the compact objects. In this talk, I will present some observational properties of neutron stars and supermassive black holes, focusing on their high-energy emission. Implication of GR effects on the observed spectral and temporal properties will be discussed.
“Magnetic black universes and wormholes with a phantom scalar”
Milena Skvortsova (VNIIMS)
Abstract: We construct explicit examples of globally regular static, spherically symmetric solutions in general relativity with scalar and electromagnetic fields which describe traversable wormholes (with flat and AdS asymptotics) and regular black holes, in particular, black universes. A black universe is a non-singular black hole where, beyond the horizon, instead of a singularity, there is an expanding, asymptotically isotropic universe. The scalar field in these solutions is phantom (i.e. its kinetic energy is negative), minimally coupled to gravity and has a nonzero self-interaction potential. The configurations obtained are quite diverse and contain different numbers of Killing horizons, from zero to four. This substantially widens the list of known structures of regular BH configurations. Such models can be of interest both as descriptions of local objects (black holes and wormholes) and as a basis for building non-singular cosmological scenarios.
