  • Atsushi Ito (Assistant Professor, Graduate School of Mathematics, Nagoya University)

Plan of the seminar: we separate each talk into two. In the first 60 minutes the speaker gives an introductory talk for non-mathematicians. After a short break, the second 60 minutes is spent for a bit more detailed talk for mathematicians (working in other areas). We welcome you joining both parts of the seminar or only the first/second half.

Abstract: We talk about Gauss maps and projective dual varieties, which are classical objects in projective geometry of algebraic varieties.
In particular, we explain Gauss maps in positive characteristic and projective dual varieties of toric varieties in characteristic 0.
