V. L. Popov

Izvestiya. Mathematics , Tome 83 (2019) no. 4, pp. 830-859.

Résumé

The first group of results of the paper concerns the compressibility of finite subgroups of the Cremona groups. The second concerns the embeddability of other groups in the Cremona groups and, conversely, of the Cremona groups in other groups. The third concerns the connectedness of the Cremona groups.

Détail

Keywords: Cremona group, compressibility, Jordan property, connectedness.
