Geometric properties of the Riemann surfaces associated with the Noumi-Yamada systems with a large parameter
The system of algebraic equations for the leading terms of formal solutions to the Noumi-Yamada systems with a large parameter is studied. A formula which gives the number of solutions outside of turning points is established. The number of turning points of the first kind is also given.
