Divergence of trigonometric lacunary interpolation
The authors prove divergence theorems for (O,M)-type lacunary trigonometric interpolation (M even) on equally spaced knots, in the uniform norm and in the weighted \(L^ p\) norm, \(p>0\). The results are given in terms of moduli of continuity with some special properties.
