Preprint Algebraic geometry and Number theory CAKE Seminar (Pancakes) - Leiden


Thursdays 10:15pm st. - 12pm, Organisers: Y. Dutta and D. Lilienfeldt

Keep in mind that it's a broad audience, so please make an effort to motivate your preprint. That being said, please also aim to present at least one proof from your preprint. We've left a break after the first 30min so that people can escape, should they want to.
