Taito Shimoji (Univ. of Osaka)
On the nilpotent quasi-projective groups (Japanese)
[ Abstract ]
The quasi-projective groups are the fundamental groups of smooth quasi-projective complex varieties. Aguilar and Campana provided the problem about the torsion-free nilpotent quasi-projective groups. The problem asks whether such groups are 2-step nilpotent or abelian groups(arXiv:2301.11232,Question26). In this talk, I introduce some my result related to the torsion-free nilpotent quasi-projective groups and the above question. In particular, the latest result suggests the existence of torsion-free nilpotent quasi-projective groups with three or more steps.
