October 10, 2023 3:00 pmWe will discuss a result which states that every projective family over ℂℙ¹ with at most two singular fibres is uniruled by rational (multi)sections. We obtain these rational curves by...

October 3, 2023 3:00 pmClassification of singularities is an interesting problem in many areas of algebraic geometry, like the minimal model program. One classical approach is to assign to a variety a rational number,...

September 19, 2023 3:00 pmI spent most of my time here cycling (or is it biking?) and thinking about algebraic cycles from a homotopical viewpoint. I will speak about the latter. In joint work...
