Practical implementation and error bounds of integer-type general algorithm for higher order differential equations

Fuminori Sakaguchi, Masahito Hayashi

In our preceding paper, we have proposed an algorithm for obtaining finite-norm solutions of higher-order linear ordinary differential equations of the Fuchsian type [\sum_m p_m (x…

General theory for integer-type algorithm for higher order differential equations

Fuminori Sakaguchi, Masahito Hayashi

Based on functional analysis, we propose an algorithm for finite-norm solutions of higher-order linear Fuchsian-type ordinary differential equations (ODEs) P(x,d/dx)f(x)=0 with P(x…
