On Korchagin's conjectures about M-curves of degree 9 in RP^2 (Stepan Orevkov, Toulouse)

16.10.2024 14:30 – 16:00

Abstract:
Anatoly Korchagin formulated 4 conjectures about the ovals of
an M-curve of degree 9 in RP^2. Now two of them are proven
(one by myself and Viro, another by Severine Fiedler-LeTouzé)
and two are disproven (by myself). Most of these results required
to involve some (more ore less) new technique.
