%0 Journal Article %T Studies on the Garnier system in two variables %A Yusuke Sasano %J Mathematics %D 2007 %I arXiv %X We study some Hamiltonian structures of the Garnier system in two variables from the viewpoints of its symmetry and holomorphy properties. We also give a generalization of {\it Okamoto transformation \it}of the sixth Painlev\'e system. %U http://arxiv.org/abs/0704.2869v1
