Abstract: We give a unified approach to error estimates for periodic
interpolation on full and sparse grids in certain Sobolev spaces. We
impose `periodic' Strang-Fix conditions on the underlying functions
in order to obtain error bounds with explicit constants.

Keywords: multivariate periodic interpolation, strang-fix conditions
