A mathematical model of the discrete 3-disk for the 3-dimensional Universe
Tetsuyuki Yukawa
A mathematical model of the distribution function for the discrete 3-disk is proposed in order to utilize in the statistical evolution equation of the 3-dimensional Universe. The m…
Birth and Growth of Two-dimensional Universe
Tetsuyuki Yukawa
A master equation for the evolution of two-dimensional universe is derived based on the simplicial quantum gravity regarding the evolution as the Markov process of a space-time lat…
From CFT Spectra to CMB Multipoles in Quantum Gravity Cosmology
Ken-ji Hamada, Shinichi Horata, Tetsuyuki Yukawa
We study the inflation process of universe based on the renormalizable quantum gravity formulated as a conformal field theory (CFT). We show that the power-law CFT spectrum approac…
Analyzing WMAP Observation by Quantum Gravity
Ken-ji Hamada, Shinichi Horata, Naoshi Sugiyama +1
The angular power spectra of cosmic microwave background are analyzed under the light of the evolutional scenario of the universe based on the renormalizable quantum theory of grav…
Making a Universe
Shinichi Horata, Tetsuyuki Yukawa
For understanding the origin of anisotropies in the cosmic microwave background, rules to construct a quantized universe is proposed based on the dynamical triangulation method of…
Space-time Evolution and CMB Anisotropies from Quantum Gravity
Ken-ji Hamada, Shinichi Horata, Tetsuyuki Yukawa
We propose an evolutional scenario of the universe which starts from quantum states with conformal invariance, passing through the inflationary era, and then makes transition to th…
