Is the group of all automorphisms of an arbitrary hyperbolic group finitely presented?

Contributor: O. V. Bogopolski

Progress

Comment of 2001: This is proved for the group of automorphisms of a torsion-free hyperbolic group that cannot be decomposed into a free product (Z. Sela, Geom. Funct. Anal., 7, no. 3 (1997) 561–593).
