2017弦理论和宇宙学高登研究研讨会 （The Gordon Research Seminar on String Theory and Cosmology）
2017 弦理论和宇宙学高登研究 研讨会
2017/2/15
The Gordon Research Seminar on String Theory and Cosmology is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and ex...
2017弦理论和宇宙学戈登学术会议（The 2017 Gordon Research Conference on String Theory&Cosmology）
2017 弦理论和宇宙学戈登 学术会议
2017/1/11
This is the second Gordon Research Conference in the series on String Theory and Cosmology, initiated in Hong Kong in 2015. Cosmology, once a philosophical subject, has matured into a precision scienc...

New Theory Turns Back Clock on Conditions Behind Universe's Origin
Turns Back Clock Universe's Origin
2016/2/22
In a new study, scientists from The University of Texas at Dallas and their colleagues suggest a novel way for probing the beginning of space and time, potentially revealing secrets about the conditio...
We present a theory for describing the evolution of a galaxy caused by stochastic events such as weak mergers, transient spiral structure, orbiting blobs, etc. This noise excites large-scale patterns ...
Pre-big bang collapsing universe from modern Kaluza-Klein theory of gravity
Pre-big bang collapsing universe modern Kaluza-Klein theory gravity
2011/10/18
We study the collapse of the universe described by a scalar field spherically symmetric collapse of a system described by a massless scalar field from a 5D Riemann-flat canonical metric, on which we m...
We work out an effective theory of accelerated expansion to describe general phenomena of inflation and acceleration (dark energy) in the Universe. Our aim is to determine from theoretical grounds, in...
Manifestly gauge invariant theory of the nonlinear cosmological perturbations in the leading order of the gradient expansion
nonlinear cosmological perturbation, gauge invariance, non-Gaussianity PACS number(s):98.80.Cq
2011/9/29
In the full nonlinear cosmological perturbation theory in the leading order of the gradient expansion, all the types of the gauge invariant perturbation variables are defined. The metric junction cond...
Cosmological Perturbation Theory With Background Anisotropic Curvature
Cosmological Perturbation Theory Background Anisotropic Curvature
2011/10/18
The theory of cosmological perturbations is extended to spacetimes displaying isotropic expansion but anisotropic curvature. The perturbed Einstein equation and Boltzmann equations for massless and ma...
The cosmological perturbation theory in loop cosmology with holonomy corrections
cosmological perturbation loop cosmology
2010/3/18
In this paper we investigate the scalar mode of first-order metric perturbations over spatially flat FRW spacetime when the holonomy correction is taken into account in the semi-classical framework of...
Quantum field theory, gravity and cosmology in a fractal universe
Fractal spacetime Models of Quantum Gravity Cosmology of Theories beyond the SM
2010/3/18
We propose a model for a power-counting renormalizable field theory living in a fractal spacetime. The action is Lorentz covariant and equipped with a Stieltjes measure. The system flows, even in a cl...
The increasing number of pulsating modes in a star leads to the
increase of the amount of information derived from the pulsation. Probing
the invisible interior of stars is a dream come true. In thi...
LOCAL ELLIPTICAL GALAXIES：SOME ASPECTS OF THEORY VS. OBSERVATIONS
Galaxies kinematics and dynamics-Galaxies elliptical and lenticular,matter dominated that the fainter ones (MB > ¡ 21:0) cD-Galaxies structure-dark matter
2009/2/10
In this paper we analyse on, the sample of the local elliptical galax-
ies, some predictions of various cosmological theories. We start with the sample of
ellipticals described in Samurovi¶c (2...
We discuss G¨odel’s universe in the context of the induced-matter theory. We show that the problem of generating G¨odel’s metric from an extra dimension is equivalent to finding an embedding of G¨odel...
