Lebesgue constants for some interpolating \(L\)-splines
The author considers interpolating splines that are bounded on the real axis, have equidistant knots, and correspond to linear differential operators of the form \(\mathcal{L}_3 := D(D^2+\alpha^2)\), where \(\alpha > 0\). Exact values for the uniform Lebesgue constant of such splines are found and compared to the Lebesgue constants of other \(\mathcal{L}\)-splines.
