| Research Abstract |
We proved that the quasiprojectivity of moduli spaces of nonsingular projective varieties in general.
It will appear as a joint paper with G.Schumacher (Annals of Mathematics 159).
I also proved that the deformation invariance of plurigenera for projective deformations of projective Manifolds. This is a very fundamental result in algebraic geometry.
Also I proved that there exsists a positive constant $nu_{n}$ such that for every $m geqq nu_{n}$ and every projective $n$-fold of general type $X$, $mK_{X}$ gives a birational embedding of $X$.
This is also very fundamental result in algebraic geometry.
