Sinc-collocation methods with consistent collocation points for Fredholm integral equations of the second kind

open access: yesCoRR, 2023
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, existing methods have the disadvantage of inconsistent collocation points. This inconsistency complicates the implementation of such methods, particularly for large-scale problems.
