On best constants in $L^{2}$ approximation

Andrea Bressan, Michael S. Floater, Espen Sande

In this paper we provide explicit upper and lower bounds on certain $L^{2}$ $n$ -widths, i.e., best constants in $L^{2}$ approximation. We further describe a numerical method to compute…

Explicit error estimates for spline approximation of arbitrary smoothness in isogeometric analysis

Espen Sande, Carla Manni, Hendrik Speleers

In this paper we provide a priori error estimates with explicit constants for both the $L^{2}$ -projection and the Ritz projection onto spline spaces of arbitrary smoothness defined o…
