Research Abstract |
In the first year, I studied the sheaf of logarithmic vector fields associated to divisors on the projective space. I obtained several results on Torelli-type theorem for generic hypersurface (Collaboration with K. Ueda) and on the freeness for hyperplane arrangements with multiplicities. In the second and third year, I studied minimality of hyperplane arrangements and applications. I obtained new presentations for fundamental groups and a characterization for vanishing twisted cohomology groups.
