| Research Abstract |
We developed a dynamical study of the sixth Painleve equation on the algebro-geometrical and moduli theoretical foundations of the Painleve system. When the parameter lies on the walls of an affine Weyl group, we established the chaotic nature of the system and proved the exponential growth of the number of isolated periodic solutions. To obtain these results, we developed a general theory of periodic points for area-preserving birational maps on a projective surface. Constructing rational surface automorphisms of positive entropy has also been discussed.
