An optimal approximation formula for functions with singularities

Ken'ichiro Tanaka, Tomoaki Okayama, Masaaki Sugihara

We propose an optimal approximation formula for analytic functions that are defined on a complex region containing the real interval and possibly have algebraic singularit…

Error estimates with explicit constants for the Sinc approximation over infinite intervals

Tomoaki Okayama

The Sinc approximation is a function approximation formula that attains exponential convergence for rapidly decaying functions defined on the whole real axis. Even for other functi…
