In the present work we consider the problem of constructing optimal grid interpolation formulas in the space $\widetilde{L_2^m}(H)$ of periodic function of $n$ variables. We find the coefficients of grid interpolation formulas.
Keywords: Sobolev space, properties of the discrete analogue of the operator $\Delta^m$
Mots-clés : optimal interpolation formula, optimal coefficients.
