CONSTRUCTING NONLOCAL FUNDAMENTAL SPLINES

In this work, we study the problem of constructing nonlocal fundamental splines on rectangular finite elements. In this case, we use the coefficients of the algebraic-trigonometric optimal interpolation formula constructed using the Sobolev method in the Hilbert space of differentiable functions. In addition, we will prove the theorem expressing the main property of these nonlocal fundamental splines.
