On 12th April, 2024, I submitted a new preprint. arXiv This is a joint work with Shin-ichi Matsumura and Niklas Müller.
On 13th–15th December 2024, we will hold a workshop: Winter seminar of Several Complex Variables in 2024

I’m Masataka Iwai, an assistant professor in Department of Mathematics, Graduate School of Science, Osaka University. Link
I’m majoring in complex geometry, algebraic geometry, and several complex variables.
I’m interested in these topics:
1. Structure of projective manifolds whose tangent bundles are “positive” (such as ample, nef, big, pseudo-effective). I established the structure theorem for projective manifolds with “positive” tangent bundles or “positive” foliations. Recently, I studied the structure of log smooth pairs whose logarithmic tangent bundles are “positive”.
2. Structure of projective manifolds whose cotangent bundles are “positive”. I proved the abundance conjecture for minimal projective manifolds with nef cotangent bundles whose numerical Kodaira dimension is one and I established the structure theorem for this projective manifolds.

Also, I studied relative anti-canonical divisors and relative versions of Fujita’s conjecture.
