We consider the Cauchy problem of the system of quadratic derivative nonlinear Schr\"odinger equations. This system was introduced by M. Colin and T. Colin (2004) as a model of laser-plasma interaction. The well-posedness of this system in the Sobolev space was obtained in our previous works (H (2014), H and S. Kinoshita (2019)). In this talk, we improve these results for conditional radial initial data by rewriting the system into radial form. This talk is based on a joint work with Shinya Kinoshita and Mamoru Okamoto.
