Campana's orbifolds, points of bounded height and fibrations
Arne Smeets
I will give a gentle introduction to the theory of Campana's orbifold
pairs, with an eye towards arithmetic aspects, in particular the study of
points of bounded height on such pairs. In particular, I will highlight
recent work of Browning-Yamagishi and
Pieropan-Tanimoto-Varilly-Alvarado-Smeets on the topic, and I will discuss
the relation with the behaviour of rational points in fibrations.
