A prototype four-dimensional Galerkin-type integral
2005
Publications of the Research Institute for Mathematical Sciences
An error functional expansion is constructed for a four-dimensional integral over [0, 1] 4 whose integrand function has a singularity structure of a type that occurs in integrals in the Galerkin boundary element method. We show with an example how extrapolation may be used to evaluate this integral.
