On the homology of Out(F_n)
Friday, 18 December, 2015 - 10:30
Résumé :
We construct cycles representing potentially nontrivial homology classes for Out(F_n) and Aut(F_n), using maps of manifolds into the moduli space of graphs. In very low rank one can verify that these are non-trivial in homology, and we conjecture that they all are.
