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…

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…
