E-mail address: genkih [at] ms.u-tokyo.ac.jp

I am a Ph.D. student of Graduate School of Mathematical Sciences, The University of Tokyo.

Research interest

I am interested in several complex variables and complex geometry.In particular, I am interested in pluripotential theoretic properties of (quasi-)plurisubharmonic functions and singular Hermitian metrics.

I am also studying the Ohsawa-Takegoshi L^2 extension theorem.

Schedule

- I will give a talk at MSJ Spring Meeting 2018.
