WitrynaGL(n,Z) and mapping class groups, the quotient of On by Out(Fn) is not compact, and the dimension of the homogeneous space does not give the best upper bound on the virtual cohomological dimension. A solution to this problem for Out(Fn) is given by considering an equivariant deformation retract of On, called the spine of Outer space. Witrynathat X is a deformation retract of Sn and hence contractible. This is why the subset X is known as the well-rounded retract of Sn.
