AN EXPLICIT VIEW OF THE HITCHIN FIBRATION ON THE BETTI SIDE FOR P1 MINUS 5 POINTS
Résumé
The dual complex of the divisor at infinity of the character variety of local systems on P^1 − {t1,. .. , t5} with monodromies in prescribed conjugacy classes Ci ⊂ SL2(C), was shown by Komyo to be the sphere S^3. We compare in some detail the projection from a tubular neighborhood to this dual complex, with the corresponding Hitchin fibration at infinity.
