From the introduction: We propose a construction of cubic spline-wavelet bases on the interval adapted for complementary boundary conditions of the first order. We show that these bases are well-conditioned and that the corresponding stiffness matrices have small condition numbers. Furthermore, we show that the adaptive wavelet frame method of S. Dahlke, M. Fornasier, and T. Raasch [Adv. Comput. Math. 27, No. 1, 27–63 (2007; Zbl 1122.65103)] with bases constructed in our paper realizes the optimal convergence rate.
