| Research Abstract |
Superstring theory suggests that our universe was created by bubble nucleation in eternal inflation. We constructed a non-perturbative formulation for such a universe. We showed that there are various phases in eternal inflation, and pointed out that the properties of our universe depend on the phase. We also proposed a new mechanism for the generation of temperature fluctuations of cosmic microwave background radiations. Superstring theory suggests that black holes are described by quantum mechanics of matrices. We computed correlation functions of such a matrix model by using analytical and numerical methods.
