Error analyses of Sinc-collocation methods for exponential decay initial value problems
Tomoaki Okayama, Ryota Hara, Shun'ichi Goto
Nurmuhammad et al. developed the Sinc-Nyström methods for initial value problems in which the solutions exhibit exponential decay end behavior. In these methods, the Single-Exponen…

Improvement of selection formulas of mesh size and truncation numbers for the DE-Sinc approximation and its theoretical error bound
Tomoaki Okayama, Shota Ogawa
The Sinc approximation applied to double-exponentially decaying functions is referred to as the DE-Sinc approximation. Because of its high efficiency, this method has been used in…

Sinc-collocation methods with consistent collocation points for Fredholm integral equations of the second kind
Tomoaki Okayama
Sinc-collocation methods are known to be efficient for Fredholm integral equations of the second kind, even if functions in the equations have endpoint singularity. However, existi…
