title: on finsler surfaces of constant flag curvature
visiting professor: mo xiaohuan
abstract：in this lecture we discuss finsler surfaces of constant flag curvature. we show that the space of those with two dimensional isometric group depends on two arbitary constants. we also give a new technique to recover finsler metric from the specified two constants. using this technique we obtain some new finsler surfaces of constant flag curvature with two dimensional isometric group.
