Optimal Spline Spaces for L^2 n -Width Problems with Boundary Conditions
Constructive Approximation(2018)
摘要
In this paper we show that, with respect to the L^2 norm, three classes of functions in H^r(0,1) , defined by certain boundary conditions, admit optimal spline spaces of all degrees ≥ r-1 , and all these spline spaces have uniform knots.
