| Research Abstract |
1. We found a new mechanism for dynamical Supersymmetry breaking. And we constructed particle-physics models based on such a new mechanism.
2. We constructed various inflation models in supergravity and discussed the primordial black-hole formation in early universe.
3. We investigated cosmological consequence of dilation presents in some string theories and pointed out a possibility that thee dilation is the dark matter in our universe.
4. We found a particle-physics model which naturally explains the large neatrino mixing observed by super kamicbande experiments.
5z We constructed a particle-physics model for the superheavy particle introduced to explain the ultra-high energy cosmic rays.
