摘要：         Via the Stokes phenomenon, the Borel-Laplace summation method plays a central role for the analytic description of the Galois differential group associated with a singular linear ODE. In the talk, we deal with a family of totally characteristic type PDEs, establishing the summability of their formal solutions in suitable Gevrey spaces. This is a joint work with Chen H. and Luo Z..
