| 概要 | Let Hom(F_n, SL(2,C)) be the set of representations from
the free group of rank n to SL(2,C).
SL(2,C) acts on this representation space by post-composition of
conjugation and the quotient space Hom(F_n, SL(2,C))/SL(2,C)
is called SL(2,C)-character variety.
The outer-automorphism group Out(F_n) acts on this quotient space.
In this talk, we investigate the dynamics of this action
and show some computer generated pictures. |
