Bestvina, Mladen; Chaika, Jon; Hensel, Sebastian

Annales Henri Lebesgue, Tome 6 (2023), pp. 1291-1348

We show that in large enough rank, the Gromov boundary of the free factor complex is path connected and locally path connected.

Nous montrons que, en rang suffisamment grand, le bord de Gromov du complexe des facteurs libres est connexe par arcs et localement connexe par arcs.
