抄録
We consider the finite difference method applied to the initial value problem for a first-order system of linear partial differential equations in the class of analytic functions. We show convergence of a scheme and existence of the analytic solution of the original differential equation by finite difference approximation. The concept of convergence is independent of that of stability as Hayakawa3)showed the fact, in 1988, for constant coefficients cases. We deal with a variable coefficients case and develop a theory in which the concept of convergence is independent of that of stability. We give some numerical results with multiple-precision arithmetic.
